A computer is a very useful machine, due to which no one has been able to tie it into a definition till date.
There is more than one complete form of computer, different people and institutions have given different definitions.
But of the number of complete forms of computers, none of them are standard complete forms.
What is Computer
Now you have come to know about the Full form of computer, now we tell you what is a computer.
A computer is an electronic machine. Many people have the misconception that computer is an English word.
|what is Computer|
But this does not mean that a computer is a calculator, because hundreds of computers work together.
Computer has many meanings and it is also very difficult to define. Therefore computers cannot be tied in one sense.
Everyone will have a different definition for computers. The definition of computer also varies depending on the task.
How Many Types of Computers
There are three types of computers
- Based on Mechanism
- Based on Purpose
- Based on Size
Based on Mechanism
They are also divided into 3 parts based on Mechanism.
- Analog Computer
- Digital Computer
- Hybrid Computer
Analog computers fall under the category of computers that are used to measure physical units.
In areas where quantities are used more, analog computers are used, such as in science and engineering, analog computers are more commonly used.
The best example of an analog is a petrol pump. Analog computers are used in petrol pumps.
The analog computer first measures the petrol coming out of the petrol pump and then shows it in liters and then calculates its value.
If we talk about digital computers, these computers count digits.
Mostly digital computers are used, this computer converts data and programs to 0 and 1 and takes them in electronic form.
These computers have many properties, due to which they are called hybrid computers.
Hybrid computers have the characteristics of both analog and digital computers, these computers are mostly used in hospitals.
The hybrid computer first measures the patient’s body temperature and then converts it into digits.
Hybrid computers accurately detect fluctuations in the patient’s health.

Based on Purpose
There are two Types of Based On Purpose Computer
- General purpose computer
- Special Purpose Computer
General Purpose Computer
These computers have the ability to perform common tasks. On these computers you can write letters, prepare documents.
The efficiency of CPU used in this computer is very low, due to which only normal work can be done in these computers.
These computers are designed for general purposes only.
Special Purpose Computer
These computers are called special purpose computers because these computers are built to perform specialized tasks.
These computers have very high CPU capacity. These computers are mostly used in the fields of astronomy, meteorology, field of war, satellite operation, medicine, physics, traffic control, oceanography, agronomy, engineering, etc.
Based on Size Computer
There are Four types
- Micro computer
- Mini Computer
- Mainframe Computer
In the early days, when the computer arrived, its size was very large, due to which it was very difficult to keep it at home.
But a much larger invention was made in 1970 which was the invention of the microprocessor.
Due to this invention, the size of the computer was so small that you could put it on a desk. This is why they are called microcomputers.
Microcomputers are also smaller in size and cost less.
The first mini computer was named PDP8. The mini computer was shaped like a refrigerator and cost $ 18,000.
This mini computer was designed by Digital Equipment Corporation. This mini computer was built in 1965.
More than one CPU is used in a mini computer and is used by computer level companies.
Mini computers are more powerful than microcomputers.
The mainframe computer is very small in size and its capacity to store data is very high.
Mainframe computers are used in large companies such as banks, government departments.
This computer can work for 24 hours without shutting down. Some mainframe computer names are IBM 4381, ICL39 Series and CDC Cyber Series.
Supercomputers are much larger in size than other computers and the most data can be stored in these computers.
Supercomputers do their work very fast, due to which they are called supercomputers.
In these computers, a lot of CPUs are used simultaneously, which greatly increases their speed of work.
These computers are used in research work in large scientific and research laboratories, which send astronauts to space for space travel, forecast the weather, create high-quality animation images.
Who Invented the Computer ?
The computer was invented by Charles Babbage in the 19th century.
Charles Babbage was a professor of mathematics, Charles Babbage is also known as the father of computers.
Many people have contributed to the computer field, but Charles Babbage’s contribution is considered the most.
The reason behind this is that in 1837 Charles Babbage first offered an Analytical engine.
What are the Components of Computers
Whatever type of computer you use, whether it is a gaming pc and a home pc, the five main components that make up a typical, current computer are:
- A motherboard
- A central processing unit (CPU)
- A graphics processing unit (GPU), also known as a video card
- Random Access Memory (RAM), also known as volatile memory
- Storage: Solid State Drive (SSD) or Hard Disk Drive (HDD)
Creating a computer without these five core components is implausible, each brand of PC has a different design and different brand components are used, but you will find five main components in each PC.
What is motherboard in computer
Motherboard is the most important part of a computer, because every part of the computer is connected to Motherboard in some way.
A computer can never function without a motherboard.
The motherboard interconnects the internal components of the computer. It is a green circuit board.
