And along with it, the demand for different level courses related to the computer, such as computer science engineering, IT, BCA, COPA etc. is increasing

Important Parts of Computer

A computer is made up of many essential parts that we can put into two categories: software and hardware


All the physical parts of a computer are called computer hardware, such as keyboard mouse monitor etc.


It is one of the most important lessons of a computer, and the computer’s processor is attached to the motherboard itself.

The port for connecting all types of input and output devices is also located on the motherboard itself.


The CPU, that is, the central processing unit, is also called the brain of the computer or processor, it processes all the data and delivers the required result.

Today most computers and laptops in the world have Intel processors and Intel’s most advanced processor is i9.




RAM is also called random access memory, everything we do on the computer is saved on the RAM at that time, and then the information gets erased when the computer is closed.

Hard drive

A hard drive is part of a computer where we can save any necessary information forever.
The operating system of the computer is also installed on this hard drive.

software parts of a compute

Talking about the software parts of a computer, the most important software is the operating system of the computer, the operating system itself performs the necessary tasks with the help of different types of hardware.
Apart from this, we can install any software on our computer according to our requirement, such as Microsoft Office, Microsoft Powerpoint, Photoshop etc.

The most famous operating system is Microsoft’s Windows which is used in about 83% of the world’s computers, the second most famous operating system is Apple’s Mac OS.

Evolution of computer

When computers were started, a computer was capable of doing only one task, but today due to the evolution, a computer can handle many tasks at a time, and artificial intelligence (AI) is coming into it.
We can divide the gradual development of computers into these five parts-

  1. First-generation computers:  Based on Vacuum tubes (1940-1956).
  2. Second-generation computers:  Based on Transistors (1956-1963).
  3. Third-generation computers:  Based on Integrated Circuits (1964-1971).
  4. Fourth-generation computers: Based on Microprocessors (1971- Present).
  5. Fifth-generation computers: Present and future- based on Artificial Intelligence (AI)

When computers started to be manufactured in the 50s, computer size was very large, the size of the first vacuum-based computer was equal to one room, and it could do only one work.

Today most people use two forms of computers, which are called desktop or personal computer, and laptop.
There is a lot of convenience in carrying laptops anywhere, so today many people do their important work on laptops.
At the same time, the computer is still used extensively in the office.
