Question 2.
How is prokaryotic cell different from a eukaryotic cell?
Answer:
Differences between prokaryotic cell and eukaryotic cell

Prokaryotic cell

Eukaryotic cell

1. Found in Bacteria, blue-green algae and , Mycoplasma.

2. Primitive nucleus called nucleoid present. Chromosome is single, circular and double-stranded DNA but no proteins (so naked), No nuclear membrane.

3. Cell wall when present, it is formed of peptidoglycan.

4. Membrane-bound Cell-organelles like mitochondria, plastids, E.R., golgi bodies etc. is absent.

5. Ribosomes are of 70 S type.

6. Small-sized (1 – 10 um).

7. Cell division by fission or budding.

Found in Protista, Fungi, Plantae and Animalia.

2. A true nucleus present. Chromosomes are two to man, linear and formed of DNA and histones. Nuclear membrane present.

3. Cell wall when present in plant cells it is formed of cellulose.

4. Membrane-bound Cell-organelles like mitochondria, plastids, E.R., golgi bodies etc. is present.

5. Ribosomes are of 80 S type.

6. Large-sized (5 – 100 /un).

7. Cell division bv mitosis and meiosis.

Question 3.
What would happen if a plasma membrane ruptures or breaks down?
Answer:
Plasma membrane maintains the shape and protects the organelles. If it gets ruptured the internal organisation will be lost and it will not be able to perform its function. Then cell wall die and contents of cell will get disintegrated.

Question 4.
What would happen to the life of a cell if there was no Golgi apparatus?
Answer:
1. The Golgi apparatus performs the function of storage, modification and packaging of materials synthesised in the cell. These materials will not be able to perform their function in its original form.
2. The formation of lysosomes will be affected.

Question 5.
Which organelle is known as the powerhouse of the cell? Why?
Answer:
Mitochondria are known as ‘power house’ of the cell. They are sites for synthesis, storage and transport of ATP (Adenosine triphosphate) commonly called energy currency.

Question 6.
Where do the lipids and proteins constituting the cell membrane get synthesised?
Answer:

Proteins are synthesised bv ribosomes.
SER is site for synthesis of lipid.
These proteins and lipids are modified by golgi apparatus to form plasma membrane.

Question 7.
How does an Amoeba obtain its food?
Answer:
Plasma membrane is flexible and it enables the cell to engulf in food and other materials from the external environment. Such a process is termed endocytosis.

Question 8.
What is osmosis?
Answer:
Osmosis. It is a special case of diffusion of water through a selectively permeable membrane. It is a passage of water from a region of higher concentration through a semi- permeable membrane to a region of low water concentration.

Question 9.
Carry out the following osmosis experiment:
Take four peeled potato halves and hollow each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,
(a) keep cup A empty
(b) put one teaspoon sugar in cup B
(c) put one teaspoon salt in cup C
(d) put one teaspoon sugar in the boiled potato cup D.
Keep this setup for two hours. Then observe the four potato cups and answer the following.
1. Explain why water gathers in the hollowed portion of B and C.
2. Why is potato A necessary for this experiment?
3. Explain why water does not gather in the hollowed out portions of A and D?
Answer:
1. The water gathers in hollowed portion of potato cups B and C due to osmosis.
2. Cup A acts as control experiment and indicates that cavity of potato will not induce any type of movement.
3. Cup A does not contain hypertonic solution hence water does not rise. In cup D, cells of potato cup being boiled cells are dead and no osmosis occurs.

Science Guide for Class 9 PSEB The Fundamental Unit of Life InText Questions and Answers

Question 1.
Who discovered cell and how?
Answer:
Robert Hooke (1665) discovered cell for the first time. He examined a thin slice of cork under the microscope. He observed that cork resembled the structure of a honey comb consisting of many hexagonal compartments and called these boxes ‘cells’.

Question 2.
Why is cell called the structural and functional unit of life?
Answer:

Cells are arranged in proper and systematic order to form a body of living organism. Thus cells serve as basic building structural units for more complex organisms.
Cell is also functional unit of life because all the metabolic activities of life take place at cell level.
Respiration, digestion, excretion and reproduction occur at cell level.
Cells contain genetic material which regulate cell functions and pass on all information to the next generation.

Question 3.
How do substances like C0₂ and water move in and out of the cell? Discuss.
Answer:
The substances like C0₂ and water move in and out of cell by the process of diffusion. There is spontaneous movement of substances from higher concentration to lower concentration. The movement of water across selectively permeable membrane is called osmosis.

Question 4.
Why is the plasma membrane called selectively permeable membrane?
Answer
Plasma membrane permits the entry and exit of selected materials in and out of the cell. It also prevents movement of some materials required within the cell. The membrane is called selectively permeable membrane.

Question 5.
Fill in the gaps in the following table illustrating differences between prokaryotic and eukaryotic cells.

Prokaryotic Cell

Eukaryotic Cell

1. Size: generally small (1 – 10 µm) = 10^-6m

2. Nuclear region ……………. and known as ………………..

3. Chromosome single.

4. Membrane-bound cell organelles absent.

1. Size: generally large 5 – 100 µm

2. Nuclear region well defined and surrounded by a nuclear membrane.

3. More than one.

4. ………………………………………………..

Answer:

4. Membrane-bound cell organelles such as mitochondria, Golgi bodies, chloroplast, etc. are present.

Question 6.
Can you name two organelles we have studied that contain their own genetic material?
Answer:

Chloroplasts
Mitochondria.

Question 7.
If the organization of the cell is destroyed due to some physical or chemical influence, what will happen?
Answer:
Each cell has certain special cell organelles. Each performs a special function. If an organization is destroyed cell will stop performing basic functions and result in its death.

Question 8.
Why are lysosomes called ‘suicidal bags’?
Answer:
Lysosomes are membrane-bound sacs filled with enzymes and this enzyme may digest their own contents if burst. They carry out autolysis (auto = self; lysis = break down) hence called “suicidal bags.”

Question 9.
Where are proteins synthesized inside the cell?
Answer:
Proteins are synthesized on the ribosomes which are attached to the surface of RER or lie freely in the cytoplasm. Ribosomes are also called “protein factories” of cells.

Question 2.
Write data types that are used in MS-Access.
Answer:
Data is stored in the computer according to its type. MS-Access supports various data types which are :
Text. The field can contain any characters. The Field Size property defines the maximum number of characters. The maximum cannot be above 255 characters.
Memo. Like a text field, but the maximum number of characters is 65,535. Access takes more time to process a memo field, so use text fields if adequate.
Number. The field can contain a number. The Field Size property defines what kind of number. ,,
Integer. A small integer. It must be in the range -32,768 to +32,767 (a 16-bit integer).

Long Integer. It must be in the range of around -2,140 million to +2,140 million (a 32-bit integer).

Double. A decimal number in the range from -1.8*10308 to +1.8*10308 with 14 significant digits (a 64-bit floating-point number).
Decimal. A very long integer with a decimal point placed somewhere. Intended for monetary calculations where rounding must be strictly controlled. In the book, we use Single or Double instead.

Question 3.
What are the advantages of MS-Access?
Answer:
Various advantages of using MS Access are :
1. Easy to install and use —Access gives data managers a fully functional, relational database management system in minutes. Like many other Microsoft applications, Access contains Wizards that walk you through each step of the way. The user interface is intuitive; accelerating data information retrieval.

2. Ease to integrate—Access works well with many of the developing software programs based in Windows. It also can be used in the front-end as back-end tables with products like Microsoft SQL Server and non-Microsoft products like Oracle and Sybase.

3. NET-friendly—Access is a go-to choice for users who plan to develop software using .NET; linking to Access database. Its graphical user interface also offers easy functionality and setup.

4. Widely popular—Microsoft Access is the most popular desktop database system in the world.

Question 4.
What do you mean by record?
Answer:
A record is sometimes referred to as a row, while a field is also known as a column. There are several ways to delete, add or edit records in a table using Microsoft Access. Users can directly manipulate records in Datasheet view. A query can be created and designed to edit and view records by simply running the query. Alternatively, a form can also be designed and created based on a database query or table then used to manipulate records.

Question 5.
What is table 7-Name the different ways to create a table?
Answer:
A table is a database object that you define and use to store data. Each table contains information about a particular subject (such as customers). A table consists of records and fields. Each record contains data about one instance of the table subject (such as a particular customer). Each record consists of one or more fields. Each field contains data about one aspect of the table subject (such as a customer’s first name or email address). Because other database objects depend so heavily on tables, you should always start your design of a database by creating all of its tables, and then creating any other objects. In Datasheet view, a table is similar in appearance to an Excel worksheet in that data is stored in rows (records) and columns (fields). The first row contains column headers (field names). In this format, the table is often simply referred to as a datasheet.

There are two ways to create a table in MS Access which are:

Creating Tables in Datasheet View
Creating Tables in Design View

Question 6.
What do you mean by Form?
Answer:
A Form is a database object which allows you to view the data one record at a time, unlike a Table where you can view the data as a continuous list of records. A Form is a convenient tool for data entry purposes because it allows the user to see all the Field entries in a single record at one time, unlike the Table view (the Datasheet View) which will often be unable to show all the data fields of a single record across the screen.

Question 7.
What is the report?
Answer:
A report is an object in Microsoft Access that is used to display and print your data in an organized manner. The Navigation Pane is where you can find all of the saved reports in the database. To view your reports, make sure that all objects are visible in the Navigation Pane. To do this, click on the Navigation Pane menu and select “Object Type” from the popup menu. Click on the Navigation Pane menu one more time and select “All Access Objects” from the popup menu. Now the Navigation Pane should display all of the tables, queries, forms, reports, and modules that are in your database. You should now be able to see all of your report objects.

3. Long Answer Type Questions

Question 1.
What are the instructions to design the database? Explain it.
Answer:
Various instructions to create a Database are :
The rule of thumb that should guide you, when planning a database, is that it becomes increasingly difficult to make changes the further along you go in the process of building a new database. If you think about it, this is true of anything you create. Here, then, are some words of wisdom that you should bear in mind when designing a database.

Taking your time upfront saves time later on:
The database you create will have a long, useful life if you take the time to plan it carefully. After you have decided on the fields to include with each record, and before you create the database, you should still invest time designing layouts for reports. Thinking about reports will cause you to think about what data you plan to put in the database.

Teamwork helps:
During the planning stage, run your ideas by others who are familiar with the kind of database you have in mind. Network among your friends. Tell them what you have in mind. Ask them to review your design. You’ll be surprised how many valuable ideas they’ll come up with that may have escaped you if you had relied on your own resources. Another good idea is to involve your students in the design. This will help them learn skills that will benefit them throughout their lives.

Keep fields simple:
The more “atomic” your fields the more flexible will be your database. Atomic here means “reduced to its simplest form.” For example, in a database of names and addresses, you would keep each part of the person’s name as a separate field. The first name should be stored by itself; the same for the middle name and last name. That way you can sort the names by first or last name. You can print a listing last name first or first name last, with or without the middle name, and so on. You will have choices. Lumping the whole name under one field limits your options.

Question 2.
Write steps to make table through datasheet view.
Answer:
Creating Tables in Datasheet View: In the Datasheet view, you can enter data into a new table without first defining the table’s structure.

To create a table in Datasheet view :
On the Create tab, in the Tables group, click the Table button. A new, blank table opens in the Object window in Datasheet view.
Adding Fields by Entering Data. You can add a new field to the table by entering data in the Click to Add column (the last column) of the datasheet; Access will automatically assign a data type based on the data that you enter.
To add a field by entering data :

1. Click in the first cell in the Click to Add column, enter the first item of data for the new record, and then press the Tab or Enter key to move to the first cell in the column to the right. Access assigns the value 1 to the ID field, assigns the name Field to the second field, and moves the Click to Add label to the third column. The icon on the row selector changes to a pencil to indicate that the record has been changed, but has not yet been saved, and the asterisk (*) icon moves to the row selector of the next row.

2. Click the pencil icon in the row selector. This saves the first record with the value 1 assigned to the ID field; subsequent records will be numbered sequentially.

3. Continue entering items of data in consecutive cells, and pressing the Tab or Enter key.

4. When you finish entering all the data for the first record, click anywhere in the row below to save the record. After you complete the first record of a new table, you should change the default field names to something more meaningful. For instructions, see the Renaming Field section of this handout. After you enter several rows of data, it is a good idea to save the table. For instructions, see the Saving Table section of this handout.

Question 3.
How does the table create in design view? Write steps.
Answer:
To create a table in Design view various steps are:

1. On the Create tab, in the Tables group, click the Table Design button. A new, blank table opens in the Object window in Design view.

To define fields various steps are:

In the Field Name column, type a name for the first field.
In the Data Type column, click the down arrow and select a data type from the list (see Figure). The Field Properties pane displays the available properties for the selected data type.
In the Description column, type a description for the field.
Repeat steps 1 through 3 to add additional fields to the table. After you add all of your fields, you must save the table before you can add any data.

Question 4.
What are the filters? Write steps to implement it.
Answer:
Filters allow you to view only the data you want to see. When you create a filter, you set criteria for the data you want to display. The filter then searches all of the records in the table, finds the ones that meet your search criteria, and temporarily hides the ones that don’t. Filters are useful because they allow you to focus on specific records without being distracted by the data you’re uninterested in. For instance, if you had a database that included customer and order information, you could create a filter to display only customers living within a certain city or only orders that contain a certain product. Viewing this data with a filter won11 be far more convenient than searching for it in a large table.

Steps to create a filler
1. Click the drop-down arrow next to the field you want to filter by. We will filter by city because we want to see a list of customers who live in a certain city.
2. A drop-down menu with a checklist will appear. Only checked items will be included in the filtered results. Use the following options to determine which items will be included in your filter :

Select and deselect items one at a time by clicking their checkboxes. Here, we will deselect all of the options except for Cary.
Click Select All to include every item in the filter. Clicking Select All a second time will deselect all items.
Click Blank to set the filter to find only the records with no data in the selected field.

3. Click OK.

Question 5.
What is sorting? How do you implement it on your document?
Answer:
Sorting is the tool in MS Access that lets you organize your data. When you sort data, you are putting it in some order. When you sort records, you are putting them into a logical order, with similar data grouped together. For example, the information in a database belonging to a bakery could be Sorted in a number of ways:

Orders could be sorted by order date or by the last name of the customers who placed the orders.
Customers could be sorted by name or by the city or zip. code where they live.
Products could be sorted by name, category (like pies, cakes, and cupcakes), or price.

You can sort both text and numbers in two ways: in ascending order and descending order. Ascending means going up, so an ascending sort will arrange numbers from smallest to largest and text from A to Z. Descending means going down, or largest to smallest for numbers and Z to A for text. First, you have to move to the column on which the sort is to be based:

Press <Tab> to move to the Surname field
Click on [Ascending] in the Sort & Filter group on the Home tab of the Ribbon. The names of the students are now in alphabetical order. Note that only the screen display is sorted – the records are still stored in the order in which they were typed, and they always will be.
Use the [Remove Sort] button to reset the data to its original unsorted order.

4. Long Answer Type Questions

Question 1.
What is IP Address? Explain.
Answer:
Unique IP Address
A Unique IP is an IP address that is specific to your domain. When you add hosting to a domain/subdomain, it’s assigned an IP on the Apache server which is shared with other sites. This shared IP address is most often the only IP you’ll need. However, certain applications may require you to add a Unique IP to your site. You can add a Unique IP to any Fully Hosted domain/subdomain hosted at DreamHost on the page.

Need of a Unique IP
Unique IPs are most commonly used with domains that have secure hosting enabled. While it is possible to use secure hosting without a Unique IP, some older browsers which do not support Server Name Indication display a certificate warning when viewing your site. While not a comprehensive list, this includes :

Windows XP versions of Internet Explorer.
The default browser in Android 2.4 is “Gingerbread” and earlier. (4.0 “Ice Cream Sandwich” and later will work correctly.)
Various older mobile browsers, including BlackBerry, Symbian OS, and older versions of Opera Mobile.

If you expect a significant number of the visitors to your secure site to be using these browsers, you will need a Unique IP.

Benefits of a Unique IP Address :
There are a lot of reasons why it is recommended to use a Dedicated IP address for a website, hosted on a Shared server, but we shall look through the main ones here:

It provides higher stability
It grants access to your website anytime you need
It is beneficial for the email sender’s reputation
It is good for a business identity
It is required for particular third-party applications/ scripts

Discuss unity in diversity in Indian society.
Answer:
We live in India and can see that the country is full of diversity. Our ways of behavior, habitat, religious values, ways of social behavior, dialect, eating habits, etc. are very much different from each other but still, we are tied with a thread of unity that we are Indians. Although we are different from each other, still live in unity and that’s why we can say that there exists unity in diversity in India.

Question 5.
Write a note on helping the needy.
Answer:
Helping others is good but it is necessary to look that help should be given to the rifeedy one. Along with this, it is a must look that help should do welfare of the needy one. If the needy one is given a thing that is not required by him then the help will be wasted. That’s why it is the duty of everyone to help needy people. Maybe you will require the help of anyone in the near future. In this way, if we help each other, society will run smoothly.

Long Answer Type Question:

Question 1.
Which values did you learn in this chapter?
Answer:

Emotions. Individuals have many emotions but they must know that when and how much of the emotion is to be used.
Balance of emotions. Maintaining a balance of emotions is necessary. For this, we need to recognize, understand, accept and control our emotions.
Social values. Every society is based on fixed values and such a society is known as a civilized society. To run society smoothly, values and rules are necessary or there will be complete chaos in society.
Unity and Diversity. People of different religions, cultures, languages, etc. live in India in peace and harmony with each other. This shows unity in diversity in India.
Helping the Needy one. We meet many people who need someone’s help to do something. We should help such people.

Source-Based Question:

Question 1.
Read the source and answer the questions that follow :
The entire creation and the world are full of diversity. Every animal, bird, every plant, every creature is unique. Even one leaf of a tree is not like another.

2. Short Answer Type Questions

Question 1.
What is E-governance?
Answer:
Governance is a framework that is developed with a combination of man and machine. The implementation of any e-governance services requires advanced technology infrastructure like web-based applications that require a dedicated server and user-friendly web interface.

Question 2.
What are the two main objectives of e-governance?
Answer:
1. To satisfactorily fulfil the public’s needs and expectations by simplifying their interaction with various online services.
2. To facilitate a speedy, transparent, accountable, efficient and effective process for performing government administration activities.

Question 3.
Write the area of E-governance in urban.

3. Long Answer Type Questions

Question 1.
Write the main characteristics of Good Governance.
Answer:
1. Good governance is transparent which means that people are able to clearly see how and why a decision was made.
2. Good governance follows the rule of law.
3. Good governance is responsive which means that government always tries to serve the needs of the entire community timely and appropriately.

Question 2.
Explain the four pillars of E-Governance.
Answer:
Fundamentally, e-Government projects would stand on four key pillars – People, Process, Technology and Resource (PPTR), Figure below. Each of the components needs to be addressed carefully and in a holistic manner, to achieve the desired results of the project, figure below :
PSEB 9th Class Computer Solutions Chapter 7 E-Governance Img 1

1. PEOPLE: As e-government projects are rolled out across the country people within and outside the government will play an increasingly important role in ensuring the success of these projects. The scale of transformation is huge and enormous resources not only in terms of money but also the expertise, skills and commitment of the people will be required.

2. PROCESS: E-Government is not just about the automation of manual records and existing processes, with all their inefficiencies. Rather, it is about transforming government processes and creating new relationships between the government and its citizens and businesses. Hence, a fresh set of process parameters and related workflow should be created, without creating unmanageable and chaotic changes, to maintain the consistency and sustainability of the process.

3. TECHNOLOGY: The Technology Challenges relate to lack of overall architecture and a road map for e-Government, lack of standards, poor IT Infrastructure, especially the poor communication networks, and, above all, adoption of the hardware approach rather than service-approach in the design and implementation of e-Gov projects. These challenges, if not addressed adequately and in time, result in an ad-hoc approach to e-Gov implementation. A few projects get implemented in isolation with big questions on their sustainability and scalability.

4. RESOURCES: New technologies demand new types of implementation models. Adopting conventional procurement methods would not take us far on the path of e-government. In the conventional approach, the project ownership lies with the public sector itself along with the responsibility for funding it and bearing the entire risk.

Question 3.
Explain the four models of e-governance.
Answer:
The followings are the four models of e-governance :

1. Government to citizens (G2C)
This model of e-governance refers to the government services which are shared by citizens. In this model, citizens visit the links of services that they want to use. This model strengthens the bond between the government and its citizen. Type of services which are provided by this model includes:-

Payment of online bills such as electricity, water, telephone bills, etc.
Online registration of applications.
Copies of land record.
Online filling of complaints.
Availability of any kind of online information.

2. Government to government (G2G)
This model refers to the services which are shared between the governments. There is lots of information that need to be shared between various government agencies, department and organizations. These types of services or information areas :

Sharing of information between police departments of various states.
Government document exchange which includes preparation, approval, distribution, and storage of all governmental documents, is also done through e-governance.
Most of the finance and budget works are also done through e-governance.

3. Government to businessmen (G2B)
Through this model, the bond between the private sector and the government is strengthened. It is used by businessmen to communicate to the government. Type of services which are provided by this model includes:-

Rejection and approval of patent are done by this model.
Payment of all kinds of bills and penalties.
Sharing of all kinds of information, rules, and data.
Complaints or any kind of dissatisfaction can be shown by this.

4. Government to employees (G2E)
This model increases the transparency between the government and its employee. Here, employees can keep a check on the functioning and working of the government and the government can keep track of its employees. Information that can be shared by this model:

All kinds of data submission (attendance record, employee record, etc.) from various government offices is done by this model.
An employee can file all kinds of complaints and dissatisfaction with this model.
All kinds of rules- regulations,s, and information for employees can be shared by this.

Question 4.
Write about E-GOVERNANCE IN HEALTH and EDUCATION.
Answer:
E-Governance provides many services in the health sector also. With the help of EGovemance, people can online check the availability of medicines, health camps, and other facilities. The following are the projects under the health area are Hospital OPD Appointment: It is the system of welfare measures started by the Chandigarh Government to make the life of citizens simpler and comfortable. HEALING: This project is started by the Kerala Government for Medical Health and Family Welfare Department,

E-Governance in the education sector is helpful in providing basic education and education facilities to children. Its aim is to provide computer education to children and online results for various classes. The following are the projects under the education field are Online Scholarship Management System: Its purpose is the distribution of scholarships and fees among brilliant and needy students. AISES (All India School Education Survey): The aim of this project is to survey the number of schools in the district which helps in the Census. This project was started by Assam Government.

Question 5.
Describe the history and development of E-governance.
Answer:
Among developing countries, India has been an early adopter of e-governance. The first wave can be considered to have evolved bottom-up. Some social entrepreneurs convinced district-level officials of the wonders of new ICTs, especially in providing convergent services to remote areas and improving transparency and oversight in this regard. The Gyandoot project in Dhar district, which begun in 2000, is considered the forerunner of what was to be a rash. of projects that built a front-end in many village communities which were supposed to be serviced by a back-end mostly in the district collectorate. The idea and the effort were to create pressure from the community front-end for the digitization of back-end departmental processes.

The latter was largely a localized effort, mostly dependent on the initiative and energy of the concerned district collector, often with some very spirited support of the district National Informatics Centre (NIC) staff. Perhaps the most organized and successful effort in this first phase of e-governance in India, roughly between 2000-05, was Rural e-Seva in the West Godavari district of Andhra Pradesh. As for community-level front-end development two initiatives, N-Logue and Drishti stand out, each of which at one time claimed to be running thousands of community telecentres across the country that could deliver e-governance services.

There is a general tendency to classify these early efforts as failures. Indeed, around 2005-06, N-Logue closed down and Drishti moved out of e-governance services. Rural e-Seva also was never scaled up. However, what is noteworthy is that in a relatively short time, these early projects created a lasting impression of new ICTs as a possible means to bring governance close to the people, and perhaps, also make it more transparent and accountable. To that extent, they had a very significant impact,

even if these initiatives themselves could not survive, due to a variety of reasons which we cannot discuss in greater detail, here. (However, if we compare this situation with the burst of the dot-com bubble in the early part of the last decade, one can see some common factors.) They created the context for the very ambitious National E-Governance Plan (NeGP), especially its flagship project, the Common Service Centres, which was inaugurated by the Government of India in 2006.

Question 1.
What is e-Government?
Answer:
The term e-Government is understood differently across the world. E- Govemment or Electronic Government is the delivery of more convenient, customer-oriented, and cost-effective public services and sharing of information through electronic media. Specifically, e-Government harnesses information and communication technologies (such as Wide Area Networks, the Internet, and mobile computing) to transform relations with citizens, businesses, and other arms of government.

Question 2.
What is the difference between e-Government and e-Governance?
Answer:
E-Govemment is the transformation of internal and external public sector relationships, through Information and Communications Technology (ICT) in order to optimize government service delivery and citizen participation. Digital society is a society or community that is well advanced in the adoption and integration of digital technology into daily life at home, work and play. E-Governance is the development, deployment, and enforcement of the policies, laws, and regulations necessary to support the functioning of a Knowledge Society as well as of e-Government.

Question 3.
What are the objectives of e-Governance?
Answer:
The strategic objective of e-Governance is to support and simplify governance for government, citizens, and businesses. The use of ICT can connect all three parties and support processes and activities. Other objectives are to make government administration more transparent, speedy and accountable while addressing the society’s needs and expectations through efficient public services and effective interaction between the people, businesses and government.

Question 4.
what are the benefits of e-Governance?
Answer:
E-Governance offers many benefits and advantages for the government, corporate sector and society. E-Governance facilitates better delivery of government services to citizens, improved interactions with business and industry, citizen empowerment through access to information, or more efficient government management. It simplifies internal operations and improves the performance of government departments while helping all sections of society to avail government services at lower cost with maximum ease of use.

Long Answer Type Questions

Question 1.
List the various services of E-governance for urban.
Ans. The followings are the various services of e-governances for urban :

1. Transportation: There are many services which are provided by e-governance in transportation like provision of booking facility of interstate transport, plans for regional transportation, time table of buses and transportation improvement program etc. The following are the projects under e-governance in transportation such as:OSRTC- The Orissa State Road Transport Corporation project was started to provide online facilities in the transportation department.HRTC- The Himachal Road Transport Corporation project provides many facilities like online booking, availability and cancellation of seats and buses etc.

2. Online payment of bills and taxes: E-Governance also provides online transactions,payment of bills, EMIs and taxes etc. The project under e-governance in online payment is FRIENDS which is started by Kerala Government to make onlinepayments of fees, water and electricity bills etc.

3. Municipal services: The services provided by municipal sector are house taxes, issuethe death certificates, maintain records of property and approval for site plans etc.The following are the projects under municipal services are:SDO Suite: This project was started by Assam Government. It provides manyfacilities by issuing certificates like permission for land sale, birth and death reportetc.

4. Rural Digital Services: It gives many social security services such as old agepension, widow and freedom fighter pension.

5. Roads and. traffic management: The services provided by road and trafficmanagement are construction and maintenance of roads, traffic management andpollution control schemes. The project under e-govemance in road and trafficmanagement is CFST (Citizen Friendly Services of Transport) which is started by Andhra Pradesh Government. It checks the pollution control level, road safety andsafety of people. ’

Question 2.
List the various services of E-governance for rural.
Answer:
The followings are the various services of e-governances for rural:

1. Agriculture: The farmers rely on the information provided by the govemmentthrough e-governance. Governments are working on many projects used in agriculture like MARKET which is approved by the Department of Marketing and inspection (DMI), Ministry of Agriculture and Government of India. ‘

2. Local information: Government provides many local information such as prices of seeds, loan rates etc. The project under e-governance in local information is EJanSamparkwhich is started by Chandigarh Government to help people access the local information in their locality to fulfil their needs.

3. Land record management: With the help of this management, huge number of land records can be maintained in a very small time. The following are the projects under land record management are : Bhooftii: It was started by Karnataka Government and known as the first E-Governanceland records management projects.Land Records Management System State Government of Punjab.

4. Panchayat: Panchayat provides many services such as issuing the birth and death certificates, various schemes for poor people and water supply and sanitation etc.

Question 3.
List the various E-Governance Services from Government To Government.
Answer:
E-Governance Services from Government to Government (G2G): It is also known as E-Administration. In this model, services are being shared between many governments. Information are shared among various government agencies, organizations and departments. The following arethe services discussed in the G2G model:

E-Secretariat: E-Secretariat provides huge, valuable and functional information of the state. In E-Secretariat,multiple departments are linked together on internet and exchange the information of various components. Italso links all the governmental departments with their headquarters and state capitals. .

E-Police: E-Police helps everyone to feel safe and secure. For this purpose, E- Police maintain two databases.First database is of police personnel which provide records (current and previous posting etc.) of persons working in police. This database helps people to find the specialization of policemen according to geographical regions and skills. Second database is of criminal records. This database provides full detail of any criminal byjust typing the name of criminal. This database also provide the past activities and area of operation of anycriminal.

E-Court: E-Court will bring a revolution in the Indian pending court cases. In India, there are a number of pending cases that produce frustration in people and will bring the system to a halt. Both consumers and the system need the change. If the system w3ill work in the same manner in future, than one day it will collapse. In E- Court, IT transforms the system into databases of cases having zero level dependency. In such systems, Judges can consider the appeals from intranet, give their decisions online by considering recorded facts of case and reduce the backlog of cases.
The success of G2G model is based on some important aspects like expenditure, the establishment of the network, planning, monitoring and controlling the performance of process resources like human and financial.

Question 4.
What are the various stages of E-governance?
Answer:
Stages of e-Governance :
It is apparent in various research studies that e-Governance is fundamentally linked with the development of computer technology, networking of computers and communication systems. In developing nations, such technologies and systems became available with an observable time lag as compared to developed nations. When appraising the e-governance model in India, it is established that with the liberalization of the economy from the early 1990s onwards, there has been a convergence in the availability of progressive technologies and opportunities in this field. The inception of e-Governance proceeded through four stages in India.

1. Computerization: In the first stage, with the availability of personal computers, the majority of Government offices are well equipped with computers. The use of computers begem with word processing, quickly followed by data processing.

2. Networking: In this stage, some units of a few government organizations are connected through a hub leading to sharing of information and flow of data between different government entities.

3. On-line presence: In the third stage, with increasing internet connectivity, a need was felt for maintaining a presence on the web. This resulted in the maintenance of websites by government departments and other entities. Generally, these web pages/websites contained information about the organizational structure, contact details, reports and publications, objectives and vision statements of the respective government entities.

4. On-line interactivity: A natural significance of online presence was opening up of communication channels between government entities and the citizens, civil society organizations etc. The main objective of this stage was to lessen the scope of personal interface with government entities by providing downloadable Forms, Instructions, Acts, and Rules.

Answer:

Primary key
Foreign key
Composite key
Natural key
Surrogate key
Candidate key
Compound key

4. Long Answer Type Questions

Question 1.
Describe Normalization. How many types of Normalization?
Answer:
Normalization is a process of organizing the data in the database to avoid data redundancy, insertion anomaly, update anomaly & deletion anomaly.
Here are the most commonly used normal forms :

First normal form(1NF)
Second normal form(2NF)
Third normal form(3NF)

First normal form (1NF)
As per the rule of the first normal form, an attribute (column) of a table cannot hold multiple values. It should hold only atomic values.

Second normal form (2NF)
A table is said to be in 2NF if both the following conditions hold :
The table is in INF (First normal form)
No non-prime attribute is dependent on the proper subset of any candidate key of the table. An attribute that is not part of any candidate key is known as a non-prime attribute.

Third Normal form (3NF)
A table design is said to be in 3NF if both the following conditions hold:
The table must be in 2NF
Transitive functional dependency of non-prime attribute on any super key should be removed. An attribute that is not part of any candidate key is known as a non-prime attribute.

In other words, 3NF can be explained like this: A table is in 3NF if it is in 2NF and for each functional dependency X-> Y at least one of the following conditions hold :
X is a super key of the table
Y is a prime attribute of the table
An attribute that is a part of one of the candidate keys is known as a prime attribute.

Question 2.
What is a file processing system? What are the disadvantages of the file processing system?
Answer:
A file processing system is a collection of files and programs that access/ modify these files. Typically, new files and programs are added over time (by different programmers) as new information needs to be stored and new ways to access information are needed. A File can store records and we can extract these records using different applications programs.
Disadvantages of File Processing System.
The conventional file processing system suffers from the following shortcomings :

1. Data Redundancy – Data Redundancy means the same information is duplicated in several files. This makes data redundant.

2. Data Inconsistency – Data Inconsistency means different copies of the same data are not matching. That means different versions of the same basic data are existing. This occurs as the result of update operations that are not updating the same data stored at different places. Example: Address Information of a customer is recorded differently in different files.

3. Difficulty in Accessing Data – It is not easy to retrieve information using a conventional file processing system. Convenient and efficient information retrieval is almost impossible using a conventional file processing system.

4. Data Isolation – Data are scattered in various files, and the files may be in different formats, writing a new application program to retrieve data is difficult.

5. Integrity Problems – The data values may need to satisfy some integrity constraints. For example, the balance field Value must be greater than 5000. We have to handle this through program code in file processing systems. But in the database, we can declare the integrity constraints along with the definition itself.

6. Atomicity Problem – It is difficult to ensure atomicity in the file processing system. For example, transferring $100 from Account A to account B. If a failure occurs during execution there could be a situation like $100 is deducted from Account A and not credited in Account B.

7. Concurrent Access anomalies – If multiple users are updating the same data simultaneously it will result in an inconsistent data state. In a file processing system, it is very difficult to handle this using program code. This results in concurrent access anomalies.

8. Security Problems – Enforcing Security Constraints in the file processing system is very difficult as the application programs are added to the system in an ad-hoc manner.

9. Observations and Conclusions – Data Redundancy may lead to Data inconsistency if redundant data are not updated simultaneously. Data inconsistency leads the system into an inconsistent state since the operations based on inconsistent data results in more inconsistency.

Question 3.
What do you mean by DBMS? Describe the advantages and disadvantages of DBMS.
Answer:
A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.
The DBMS has a number of advantages as compared to the traditional computer file processing approach. The DBA must keep in mind these benefits or capabilities during designing databases, coordinating and monitoring the DBMS.

The major advantages of DBMS are described below :

Controlling Data Redundancy
Data Consistency
Data Sharing
Data Integration
Integrity Constraints

Disadvantages of Database Management System (DBMS):
Although there are many advantages the DBMS may also have some minor disadvantages. These are :

Cost of Hardware & Software
Cost of Data Conversion
Cost of Staff Training
Appointing Technical Staff

Question 4.
What is an entity? Write the types of entities in DBMS.
Answer:
An entity can be a real-world object, either animate or inanimate, that can be easily identifiable. For example, in a school database, students, teachers, classes, and courses offered can be considered entities. All these entities have some attributes or properties that give them their identity. An entity set is a collection of similar types of entities. An entity set may contain entities with attributes sharing similar values. For example, a Student set may contain all the students of a school; likewise, a Teachers’ set may contain all the teachers of a school from all faculties. Entity sets need not be disjoint.

The Entity-Relationship (ER) model consists of different types of entities. The existence of an entity may depend on the existence of one or more other entities, such an entity is said to be existence dependent. Entities whose existence not depending on any other entities are termed as not existence dependent. Entities based on their characteristics are classified as follows.

Strong Entities
Weak Entities
Recursive Entities
Composite Entities

Strong Entity Vs Weak Entity
An entity set that has a primary key is termed a strong entity set. An entity set that does not have sufficient attributes to form a primary key is termed a weak entity set. A weak entity is existence-dependent. That is the existence of a weak entity depends on the existence of an identifying entity set. The discriminator (or partial key) is used to identify other attributes of a weak entity set. The primary key of a weak entity set is formed by the primary key of identifying the entity set and the discriminator of the weak entity set. The existence of a weak entity is indicated by a double rectangle in the ER diagram. We underline the discriminator of a weak entity set with a dashed line in the ER diagram.

Recursive Entity
A recursive entity is one in which a relationship can exist between occurrences of the same entity set. This occurs in a unary relationship.

Composite Entities
If Many too Many relationships exist we must create* a bridge entity to convert it into 1 to Many. Bridge entity composed of the primary keys of each of the entities to be connected. The bridging entity is known as a composite entity.

Question 5.
What do you mean by data models? Write the parts of it.
Answer:
Data Models are fundamental entities to introduce abstraction in a DBMS. Data models define how data is connected to each other and how they are processed and stored inside the system. The very first data model could be a flat data model, where all the data used are to be kept in the same plane A data model organizes data elements and standardizes how the data elements relate to one another. Since data elements document real-life people, places, and things and the events between them, the data model represents reality, for example, a house has many windows or a cat has two eyes. Computers are used for the accounting of these real-life things and events and therefore the data model is a necessary standard to ensure exact communication between human beings.

A data model consists of two parts as shown in the figure:

DDL – Data definition language

2. Create separate tables for each group of related data and identify each row with a unique column (the primary key).

Question 3.
What is Data?
Answer:
Data is a plural of datum, which is originally a Latin noun meaning “something given.” Today, data is used in English both as a plural noun meaning “facts or pieces of information” and as a singular mass noun meaning “information”. In computing, data is information that has been translated into a form that is more convenient to move or process. Relative to today’s computers and transmission media, data is information converted into binary digital form.

Question 4.
Define Database.
Answer:
A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. In computing, databases are sometimes classified according to their organizational approach. The most prevalent approach is the relational database, a tabular database in which data is defined so that it can be reorganized and accessed in a number of different ways. A distributed database is one that can be dispersed or replicated among different points in a network. An object-oriented programming database is one that is congruent with the data defined in object classes and subclasses.

Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Typically, a database manager provides users the capabilities of controlling read/ write access, specifying report generation, and analyzing usage.

Question 5.
What is DBMS (Database Management System)?
Answer:
A Database Management System (DBMS) is a set of computer programs that controls the creation, maintenance, and use of a database. It allows organizations to place control of database development in the hands of database administrators (DBAs) and other specialists. A DBMS is a system software package that helps the use of an integrated collection of data records and files known as databases. It allows different user application programs to easily access the same database. DBMSs may use any of a variety of database models, such as the network model or relational model. In large systems, a DBMS allows users and other software to store and retrieve data in a structured way.

Instead of having to write computer programs to extract information, users can ask simple questions in a query language. Thus, many DBMS packages provide Fourth-generation programming language (4GLs) and other application development features. It helps to specify the logical organization for a database and access and use the information within a database. It provides facilities for controlling data access, enforcing data integrity, managing concurrency, and restoring the database from backups. A DBMS also provides the ability to logically present database information to users.

Question 6.
What is the need for DBMS?
Answer:
A database management system (DBMS) can help address the employee count scenario and a range of even more complex situations related to cost, order status, or inventory management by presenting the same data to everyone in the business at the same time. A DBMS also eliminates the frustrating hunt for the right version of the right spreadsheet on a vast and disorganized network drive.

As businesses grow, the volume of data they accumulate grows exponentially. Managing this data deluge becomes increasingly difficult just at the moment when superior data management becomes more important to business success.
As businesses expand, more sophisticated tools are needed to manage data. Tools that serve start-ups well are overwhelmed by the demands faced by larger businesses,
A database management system (DBMS) is a powerful tool used to store data, secure it, protect it and make it quickly available to people who need it.
A DBMS enables a business to squeeze more value from the data it collects for improved decision-making.

Question 7.
What are the Advantages and Disadvantages of DBMS?
Answer:
The advantages and disadvantages of DBMS are as follows :

Advantages :

Reduced data redundancy
Reduced updating errors and increased consistency
Greater data integrity and independence from applications programs
Improved data access to users through the use of host and query languages
Improved data security
Reduced data entry, storage, and retrieval costs
Facilitated development of new applications program

Disadvantages :

Database systems are complex, difficult, and time-consuming to design
Substantial hardware and software start-up costs
Damage to database affects virtually all applications programs
Extensive conversion costs in moving form a file-based system to a database system
Initial training is required for all programmers and users.

(B) Answer in 1-2 sentences:

Question 1.
Define GM crops.
Answer:
By using specialized genetic engineering technologies crop can be genetically modified by the transfer of gene of other plant or organism into the crop. GM stands for Genetically Modified crops.

Question 2.
Differentiate BG-I from BG-II.
Answer:
BG-I stands for Bollguard-I hybrid and BG-II stands for Bollguard-II. These are cotton hybrids. BG-I contained only one Bt gene. Whereas BG-II contains two Bt genes. BG-I can withstand the attak of American Bollworm only whereas BG-II can withstand the attack of all the four types of Bollworm namely American Bollworm, Spotted bollworm, Pink Bollworm and Tobacco Caterpillar.

Question 3.
Why Bt cottons remain safe from any damage by the bollworms?
Answer:
Bt cotton contains Bacillus Thuriengiensis, a soil bacterium. This gene produces crystalline protein in the plant, which is highly toxic for the bollworm, insects-pests of cotton. When bollworm feeds on flower bud or flower or boll of a Bt cotton plant, digestive system of the insect gets damaged and it gets killed. This way ‘cotton crop is saved from the harmful insects.

Question 4.
What is precision farming? List its benefits.
Answer:
This is a new concept of farming. The main objective behind this concept is to use judiciously the various inputs as decided and calibrated by various scientific technologies so as to save natural resources and to increase the yield of the crop. Insecticides, fertilizers, weedicides etc. are used in measured quantity accurately and different amounts are used in different sections of a field according to the need. This way these inputs are not wasted and yield is also increased. It also does not pollute the environment.

Question 5.
Discuss methods that need to be adopted for judicious use and saving of water.
Answer:
If leveling of field is done by using laser land leveler a lot of water is saved. Similarly use of tensiometer in rice crop helps in deciding when and how much irrigation is needed for the rice crop. This helps in saving water.

Question 6.
What may be the impact of climate change on wheat crop?
Answer:
It can adversely effect the yield of wheat. If there is increase in temperature during February and March wheat production will reduce.

Question 7.
Why temperature increases inside a greenhouse?
Answer:
Houses which are made up of plastic sheets or glass in which plants are grown are known as green houses. Sun rays can enter the green house but the infrared rays (heat rays) cannot come out from such a house. Thus Temperature increases in the green house.

Question 8.
List names of different Green House Gases.
Answer:
Do yourself.

Question 9.
What was the impact of Bt cotton varieties on cotton production in Punjab?
Answer:
Bt cotton was introduced in Punjab in 2006. Before this cotton crop in Punjab was totally ruined due to attack of American Bollworm. Lint yield reduced to only 2-3 quintal per acre. But with Bt cotton lint yield increased to 5 quintals per acre and use of insecticides were also reduced.

Question 10.
List names of important techniques used in Precision Farming.
Answer:
Important techniques used in precision farming are- sensors, G.P.S. satellite technology etc.

Question 1.
Which GM crop is being cultivated in “Punjab”? Explain its benefits.
Answer:
In Punjab G.M. crop of cotton in cultivated. It is called Bt cotton. Now there are some other GM crops prepared e.g. Brinjal, Maize, Soyabean and Rice. In Bt crops gene of a soil Bacterium Bacillus Thuriengiensis is introduced in the plants. This produces a crystalline protein in the plant, which is highly toxic for the bollworms. The insects eat this protein and their digestive system is damaged and thus they are killed in 3-4 days. Bt varieties can bear the attack of American bollworm, pink, Tobacco, spotted bollworms. In Bollguard-I hybrid of cotton only one Bt gene was introduced but in Bollguard-II two Bt genes were introduced cultivation of Bt cotton started in Punjab in 2006. Before its cultivation lint yield was only 2-3 quintal per acre but with Bt cotton lint yield increased to 5 quintal per acre. There in no need to use insecticides and thus environment also does not get polluted.

Question 2.
What are the dangers and risks associated with GM crops?
Answer:
Ever since the introduction of GM crops, many organizations, social activists, human welfare groups and even some of the scientists are against such GM crops. They think such crops are very harmful to the humans, plants, environment, species of cultivated plants, biodiversity of plants in long run. Although, there are no such evidences till date in favour of such fears or arguments. But some of the countries have banned the cultivation of such GM crops.

Question 3.
List objectives of PPV & FR Act. When was this act introduced?
Answer:
Main objective of PPV and FR act was to recognize and protect the farmers’ rights.

Plant breeder has right on the new variety of plant which he produced.
Farmers who are .cultivating a variety traditionally on their field or a landrace of a variety for which farmer have common knowledge can be registered as farmers’ variety.

Question 4.
How Green House Gases affect the climate?
Answer:
Green house gases have bad effect on the environment. Because of increase in the density of green house gases in the atmosphere, temperature of the globe is increasing, over the past 100 years it is estimated that earth has warmed by 0.5°C. And an estimate says that by the year 2050 temperature may increase by 1.8 to 4.0°C. As a consequence of this increase in temperature polar ice will melt, ocean water level will become higher, warm days become will become more warmer and cold days become colder. Rains will become erratic and seasons will start overlapping.

Question 5.
Discuss impact of climate change on agriculture.
Answer:
Climate changes can affect the agricultural activities. Due to global warming temperature on earth is increasing which can affect the environment in many ways.

Increase in temperature will effect life time of crop, crop rotation and time of cultivation of crops is also affected.
Due to increase in temperature and moisture content in the atmosphere many diseases and some new type of insects will damage the crop.
Increase in temperature in the month of Feb-March will affect the production of wheat.
There is uncertainly in rains and production decreases.
Fall in night temperature will also reduce yield. ,
There may be good affects on agricultural production in many countries.

Answer:
Its clear message is to consider a field as consisting of many sections, there may be a problem of one type in one section and another type of problem in another section. Without knowing the problem of a particular section do not apply fertilizers or spray pesticides etc. If the soil in a section of the field is deficient in a particular mineral. Apply that particular fertilizer in only that section of the field and not in the whole of the field.

Question 7.
By how much temperature of the surface of the earth has increased over the last 100 years. Why?
Answer:
The temperature of the surface has increased by 0.5°C over the last 100 years. This is due to global warming.

Long Answer Type Questions:

Question 1.
Write about Green House Gases and greenhouse principle. How is it related to the earth?
Answer:
Greenhouse gases are Carbon dioxide, Nitrogen oxide, Chlorofluorocarbon, Methane, etc. Houses that are made up of plastic sheets or glass in which plants are grown are known as greenhouses. Sun rays can enter the greenhouse but the infrared rays (heat rays) cannot come out from such a house. Thus temperature increases in the greenhouse.

Greenhouse gases are there all around the globe. These allow the sunlight to enter into the earth’s atmosphere but do not allow the infrared rays (heat rays) to go back into space. Thus they are responsible for global warming. The temperature of the earth is increasing and its bad effects can be floods, drought, change in time of monsoon, etc.

Question 2.
Write some factors responsible for climate change?
Answer:

Increased concentration of greenhouse gases like C02, CH4, etc.
Burning of fossil fuels like petrol and coal etc.
Deforestation on a large scale.
Industrialization and urbanization.
Excessive use of agrochemicals.
