COMPUTER full form or meaning is Common Operating Machine Purposely used for Technological and Educational research.
By the way, a computer is not an acronym and is the name of an electronic device.
A computer is a simple machine that we can program for a lot of logical and arithmetic functions, and it executes our work according to our instructions.
in simple words, a computer is an electronic device that makes our work easy, and any computer that has been programmed for some set of works, it performs that task or works quickly and correctly.
as the computer is not an Indian word, so many times people want to know the full form of it, and many people use common operating machine purposely for technical and educational research as a full form of computer.
Charles Babbage is called the father of computers, he developed the plan of the analytical engine in 1830, which later came to be known as the computer.
What is a computer?
A computer is an electronic device that performs our essential tasks according to pre-determined instruction.
The computer is capable of storing data, making necessary changes to it, and providing data on demand again.
Today, a lot of our essentials are done with the help of computers, such as typing a document, playing games, sending emails, browsing the web, etc.
You will be surprised to know that our mobile has also become a mini-computer, and that is why today the mobile is capable of doing many of our important tasks simultaneously.
Whether a factory, college, electricity department, or our car, computers are being used everywhere, and that is why our cars or new plants are becoming smart.
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 on 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.
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 in it.
We can divide the gradual development of computers into these five parts-
- First-generation computers: Based on Vacuum tubes (1940-1956).
- Second-generation computers: Based on Transistors (1956-1963).
- Third-generation computers: Based on Integrated Circuits (1964-1971).
- Fourth-generation computers: Based on Microprocessors (1971- Present).
- 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.
Benefits of Computers
Today our way of working has changed completely due to the computer. Following are some advantages of computer-
The biggest advantage of a computer is that a computer can do many things at once, today’s computer is following thousands of instructions every second.
Any computer performs any work according to the given instructions and pre-determined rules without any fault.
Today’s advanced computer is capable of doing big things in a moment.
