What is Computer

Here we will talk about what is Computer. In simple language, a computer is an electronic device. You might already know this answer. So you must be thinking, why again this article about which we already know everything.

Just wait. Today I want to tell you what the basic computer is, you may know some of it in advance, but my objective is that you should be given information about the whole computer and not half of it. I know you know basic computer information. But do you know how it works, who made it before, through which kisses it has passed. How many changes have been seen in the characteristics of computers in so many years.

The computer that we are using today is the result of years of hard work of many scientists behind it. At the same time, with half the incomplete knowledge, you have full knowledge. Today, I want to give you complete information about this machine along with what you call this article, what is the main part of it, what is the full form of computer and how does it work. Then, let's start the delay and know what a computer is.

What is Computer?

A computer is a machine that performs tasks according to certain instructions. There is an electronic device, which is designed to work with information. The word computer is derived from the Latin word "computare". This means calculating or calculating.

It has three main functions. The first is to take the data which we also call Input, the second task is to process that data and the other task is to show the processed data which is also called Output.

Input Data →  Processing → Output Data

What is Computer?

Who invented computer?

 The father of modern computers is called Charles Babbage. Because he was the first to design a mechanical computer, which is also known as Analytical Engine. In this, data was inserted with the help of Punch Card.

So we can call a computer an advanced electronic device that takes raw data from the user in the form of input, then processes that data through a program (set of Instruction) and finally the result as Output Publishes. It processes both numerical and non numerical (arithmetic and logical) calculations.

What is the full form of computer?

Technically there is no full form of computer. Yet the computer has an imaginary full form,

C – Commonly,
O – Operated,
M – Machine,
P – Particularly,
U – Used for ,
T – Technical and
E – Educational,
R – Research

History of Computer

It cannot be properly verified that the development of computers has been started since. But officially computer development has been classified according to generation. They are divided into 5 parts from the main tower.

When it comes to the generation of computer, then it means that computer's generations in Hindi. As the computer grows, they are divided into different generations to make it easier to understand them properly.


First Generation Computer – 1940-1956 “Vacuum Tubes”
The first generation computers used Vaccum tubes for circuitry and Magnetic Drum for memory. They used to be very big in size. A lot of power was used to run them.

Being too big, it also had a lot of heat problem due to which it was also malfunctioned many times. Machine language was used in them. For example, UNIVAC and ENIAC computers.

Second Generation Computer – 1956-1963 “Transistors”

In second generation computers, transistors replaced vaccum tubes. Transistor took very less space, was smaller, was faster, was cheaper and was more energy efficient. They used to generate less heat than the first generation computers, but still there was a problem of heat in it.

High level programming languages ​​such as COBOL and FORTRAN were used in them.


Third Generation Computer – 1964-1971 “Integrated 
Integrated Circuit was first used in third generation computers. In which the transistors were cut into small silicon chip which is called Semi Conductor. Due to this, the ability to do computer processing increased to a great extent.

For the first time, monitors, keyboards and operating systems were used to make computers of this generation more user friendly. It was first launched in the market.

Fourth Generation Computer – 1971-1985 “Microprocessors”
It is typical of the Forth generation that Microprocessor was used in it. Thousands of integrated circuits were embedded into a single silicon chip. This made it very easy to reduce the size of the machine.

The use of microprocessor increased the efficiency of the computer even more. This work was able to do a lot of calculations.

Fifth Generation Computer  – 1985-present “Artificial Intelligence”
Fifth generation belongs to today's Dor, where Artificial Intelligence has established its dominance. Now, many new technologies like Speech recognition, Parallel Processing, Quantum Calculation have been used in new technology.

This is a generation where due to the computer's artificial intelligence, the ability to make decisions on its own has come. Gradually all its works will be automated.


Who invented computer?
Who is the father of modern computer? Many such people have contributed to this Computing Field. But more of all this is contributed by Charles Babage. Because he was the first Analytical Engine came out in 1837.

The concept of ALU, Basic Flow Control and Integrated Memory was implemented in this engine. Today's computer was designed by basing itself on this model. This is why his contribution is the highest. Then he is also known as the father of the computer.


Definition of computer
There are many components of any modern digital computer but some of them are very important such as Input device, Output Device, CPU (Central Processing Unit), Mass Storage Device and Memory.

accepts data               Input
processes data      Processing
produces output      Output
stores results               Storage

How does the computer work?
Input (Data): Input is the step in which Raw Information is inserted into the computer using Input Device. It can be a letter, picture or even a video.

Process: The data input during the process is processed according to the instruction. This is a completely internal process.

Output: The data that has already been processed during the output is shown in the Result. And if we want, we can also save this result and keep it in memory for future use.
