Today we are going to give you information about computers, so read this article carefully. If you have any questions connected to the computer, then you can ask us by commenting. Let us know everything you need to know about the computer if you want to learn the computer.

What is the definition of a computer and what is a computer, these questions are often asked in examinations, but today the computer that is found in your home is the same computer, or if we say that the thermometer in your house is also a computer. If you believe, then let’s try to know what a computer is.


What is Computer Definition?

Let’s first know the introduction of computer. The word computer is derived from the word “Compute” in English, which means “computation”. That is why it is also called calculator or computer or computer machine.

It was invented for calculating a simple computer calculating machine, like your calculator.

Computer Definition in Hindi

“Computer” शब्द की उत्पत्ति लैटिन भाषा के ‘Computare‘ शब्द से हुई है, जिसका अर्थ है – गणना करना। कंप्यूटर को हिंदी में “संगणक” कहा जाता है। कंप्यूटर एक इलेक्ट्रॉनिक उपकरण (Electronic Device) है,

जो उपयोगकर्ता से डेटा (Data) और निर्देशों (Instructions) के रूप में इनपुट (Input) प्राप्त करता है।

एक बार इनपुट डेटा प्राप्त होने के बाद, यह डेटा की प्रोसेसिंग (Processing) शुरू कर देता है और उपयोगकर्ता के निर्देशों के अनुसार हमें आउटपुट (Output) प्रदान करता है। Read More

What is Computer system?

The process of functioning of a computer is completed in a phased manner. Input → Processing → Output

For input, you use an input device such as a keyboard, mouse, etc. Also, command or direct the computer through software, or enter data.


This is the second part of this process. In this, the command or data given by you is processed by the processor according to the information and instructions available in the software.

The third and final part output is given by the computer to the output of the information processed based on the command given by you. Which you get by the output device.

A computer requires both software and hardware to function properly. If spoken in direct language, then these two complement each other. Without hardware software is useless, and without software hardware is useless.

Meaning hardware commands are given from computer software. How to make any hardware work His information is already inserted in the software.

Many types of hardware are connected to the CPU of the computer, making the synergy between all of them work to run the computer properly. System software means operating system.

All Types of Computers

But computers do not mean just the computers that are commonly found in your homes, the computer is classified in three ways on the basis of working method.


Three types Of Computers

  1. Analog Computer 
  2. Digital Computer 
  3. Hybrid Computer

These three have their own specialties, so let’s know what is digital, analog and hybrid computer

What is Analog Computer?

They are used in measuring physical units pressure, temperature, length, speed etc., let’s understand a little more, talk about meteorological pressure of air, moisture or rain in the atmosphere or the lowest or most today, What was the temperature. Analog computers have been made to collect all these data.

Examples of analog computers

  • Rain gauge – It measures the amount of rainfall at a particular place.
  • Hygrometer – It measures the humidity prevailing in the atmosphere.
  • Anemometer – It measures the power and speed of air.
  • That is, all these analog computers collect physical data.

What is a Digital Computer?

Digital computers are computers that you usually use. In our homes, in offices, in which data is fed digitally and output is obtained.

Most digital computers are used, and are generally available in markets. Digital computers convert data and programs into 0 and 1 ie binary and take them in electronic form.


Examples of digital computers

  • Desktop – Many people use desktop computers for their homes, schools and their personal work. They are designed in such a way that we can keep them on our desk. They have many parts such as Monitor, Keyboard, Mouse, Computer Case.
  • Laptop – You must have known about laptops that are battery-powered. They are very portable so that they can be taken anywhere and anytime.
  • Tablet – Now let’s talk about the Tablet which we also call Handheld Computer as it can be easily caught in handguns.

It does not have Keyboard and Mouse, just a touch sensitive screen which is used for typing and navigation. Example- iPAD.

  • Servers – A server is a computer of some sort that we use to exchange information. For example, whenever we search for something on the Internet. All those things are stored on the server.

What is Hybrid Computer?

Hybrid computers have the properties of both analog computers and digital computers. These are considered more reliable than computer analog and digital.

Their job is to provide data received from analog कंप्यूटर in digital form, they are most used in medical, meteorology.

History of Computer – Generation of Computer

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


When it comes to the generation of computers, it means that the computer’s victims like computers grow. They were divided into different generations. So that it is easy to understand them properly.

First Generation of 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 electricity was used to run them.

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

Second Generation of Computers – 1956-1963 “Transistors”

In second generation computers, transistors replaced vaccum tubes. Transistors used to take very less space, they were smaller, faster, were cheaper and were 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 ​​like COBOL and FORTRAN were used in them.

Third Generation of Computers – 1964-1971 “Integrated Circuits”

Integrated Circuit was first used in third-generation computers. In which the transistors were cut and inserted into the silicon chip. Which is called Semi-Conductor. Due to this, the ability to do कंप्यूटर 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 launched in the market for the first time.

Fourth Generation of Computers – 1971-1985 “Microprocessors”

This is the specialty 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 कंप्यूटर even more. This very work was able to do a lot of calculations.

Fifth Generation of Computers – 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 are being used in the new technology.

They are such a generation. Where the कंप्यूटर has Artificial Intelligence, the ability to make decisions on its own has come. Gradually all its works will be automated.

Who Invented Computer?

Father Of Computer Charles Babbage

Who is called 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 कंप्यूटर 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.
