(Boys and girls of standard VI were playing in the playground).

Siva: Hey Salim, I saw your dad coming with a big parcel yesterday. I guess you could have bought a new television, Am I right?

Salim: It’s not a TV Siva. We bought a new computer.

Malar: Oh, I see. computer! I had seen it in Textile shop used for billing.

Selvi: Malar, not only in textile shops, but also it’s used in Railway stations, Banks, ATM’s and in many places. It is used even in our local post offices. Nancy: Hey! I had seen it in my school. 

Salim: Is it only in your school? Nancy, I think your father is also having a computer.

Nancy: Is my father having a computer?! Without my knowledge? I’m sure that my father doesn’t have computer. He has only a mobile phone.

Salim: That’s what I say your father’s mobile phone is also like a computer. 

Nancy: Oh no Salim? What do you mean? How can a mobile phone compared with a computer?

Salim: Nancy, we usually think that computer should be like a big TV and a box attached with it, But computers are available in different shapes. The works which are done with a computer can also be done using a smart phone. There may be difference in their speed, but their operations remain the same. The big computers are shrunk into small smart phones nowadays because of the technological development. Most of us think that smart phones are only to make calls because of its’ handy look But it isn’t so.

Selvi: What about laptops and tablets? Are they same like the computers we usually think of?

Salim: Yes, They are all the same. These are different types of computers. But their performance vary according to their capacity.

Siva: That’s ok Salim, why do you need a computer in your home? What will you do in that?

Salim: I can use it to draw, paint, play games and I can learn and develop my general knowledge.

Selvi: Salim, you know more about computers!

Salim: I know very less about computers. As my dad uses computer in his office, he knows much about it. I shared very little of what I have learnt from my dad.

(All the children stood up when the teacher came and stood near them)

Teacher: What is going on?

Children: We are discussing about the computer sir.

Teacher: Oh, I see, that’s nice. I will explain you in detail. Firstly I will explain you about what is a computer? Computer is an electronic device that process the data and Information according to our needs. We can save the data and convert it into information. Computers are used in many ways.

Malar: We are eager to know who has invented the computer?

Teacher: In the beginning of 19th century, Charles Babbage, a professor in Mathematics has designed an analogue computer. He is known as the father of computer.

The basic structure designed by him is being used in all computers. Similarly, Augusta Ada Lovelace is admired as the first programmer as she developed essential commands for the mathematical operations.

Nancy: Sir, can you tell us which device was used before the invention of computer?

Teacher: In the early stage, there was no computer. Initially the people used a tool called abacus for calculations.

Later, they started using a device called calculator for calculation.

Selvi: Wow! It’s really interesting sir, then when did computers come into use Sir?

Teacher: Good question Selvi. Computer didn’t come directly from abacus. The computers that we use today belongs to fifth generation.

Nancy: Oh! was there four more generations previous to this?

Teacher: Yes, Nancy you are correct.

Siva: Sir! Can you explain us about the five generations?

Teacher: In First generation computers, they used Vacuum tube

In Second generation computer, they used Transistor

In Third generation computer, they used Integrated Circuit

In Fourth generation computer, they used Micro processor

In Fifth generation computer - Now they use Artificial Intelligence

Selvi: Sir, we are eager to know more about the present computers which we use sir?

Teacher: Data and information are the two important elements in computers.

Malar: Sir, What is meant by data?

Siva: Then, what is application software?

Teacher: Data is the information that has to be processed. It cannot be used directly by us. Generally, they are in the form of numbers, alphabet and images.

Siva: Sir… then what is information?

ENIAC (Electronic Numerical Integrator and Computer) was the first Computer introduced in the year 1946. This is the first General purpose computer.

Teacher: Information is a form of processed data.

Siva: What is software and hardware, Sir?

Teacher: The commands or programs that are used in computer are called Software. This software can be divided into two types.

1. Operating software

2. Application software.

Nancy: What is Operating Software?

Teacher: Software that is used to operate the computer is called operating software. I think you are familiar with Windows and Linux

Teacher: Application software is a software that is used to run a particular program. For example, the software used for painting, playing games in computer.

Nancy: Oh! I have learnt much information about computers today sir!.

Malar: Ok Sir, then what is hardware?

Teacher: The parts that are available in the computer that helps the software to works is a hardware.

Salim: Sir, please tell us more about it

Teacher: Yes, sure I will. Whatever we want to send to a computer is sent through a device called input device. For example, the keyboard, mouse and other input devices.

The data or information that has been sent to the computer are displayed out or reproduced through some devices these are called as output devices. For example, printer, monitor and so on.

Nancy: Ok Sir, then what is CPU?

Teacher: It is the central processing unit. You will learn and understand more about CPU in your higher classes.

All Children together: Thank you so much, Sir. Today we have learnt and understood more information about
