  3. Mainframe Computer
  4. Supercomputer

Micro 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.

Mini Computer

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.

Mainframe Computer

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.
