What is the Definition of a Computer?

A computer is a programmable machine that can perform complex mathematical and logical operations automatically. In simple words, a computer is a device that processes the data input provided by the user, converts it into required information, and presents it to us as output. The word computer is derived from the English word “compute”, which literally means to calculate.

What is the full form of a Computer?

The word “computer” is simply a word derived from the English word “compute”, meaning to calculate, and is not an abbreviation. There is no real full version for computers. You will find many articles on the internet explaining the complete form of the computer. But this is just a myth. However, if you want to know the most popular so-called complete form of computer, then I am presenting it in this article just for your information.

Inventor and father of Computer

After many debates about who should be credited with the invention of the computer, an English mechanical engineer named Charles Babbage is called the Father of the Computer, because the modern computer has a lot in common with the Analytical Engine he invented.

Development of Computers

In ancient times when computers were not invented, people usually counted with their fingers, sticks, stones, etc. Then when the human brain gradually started to develop, people started to invent different types of devices. Abacus is believed to be the first human-made computer. We have no information about when exactly the Abacus was invented. Then with the passage of time, more and more types of calculating machines were invented. Some of the notable devices are Napier's Bones, Slide Rules, Pascal's Adding and Subtraction Machine, Punch Card System, Babbage's Analytical Engine, etc.

Generations of Computers

First Generation [1940 – 1956]: Vacuum Tube

Second Generation [1956 – 1963]: Transistors

Third Generation [1964 – 1971]: Integrated Circuit

Fourth Generation [1971–Present]: Microprocessor

Fifth Generation [Present – Next]: Artificial Intelligence

Working Process of Computers

A computer generally works through 4 processes: receiving input or instructions from the user, processing the data based on that input, storing the processed data in a storage device, and displaying it as an output to a specific output device. Input: Any information or instruction sent to a computer by a user is called input. Information is transmitted to the computer through various types of input devices such as a keyboard, mouse, etc.

Processing (Processing): All the information that the user sends to the computer, is converted into usable information by changing or processing in a special way by the CPU at this stage.

Storage: At this stage, the computer stores the converted data in the storage device for future use.

Output: The data converted after processing is called output. The computer processes the input data and sends it to output devices such as monitors, printers, speakers, etc., which the user can see or hear.

Main Parts of Computer

Everything that we can touch in a computer usually belongs to hardware. Just like the human body, a computer is made up of different parts. And software is needed to manage all these parts and coordinate them all.
