Electronic story

Computer History

It is very difficult to determine the exact origin of the computers. But according to some experts, the computer was available during World War II. Also, at that time they were used to store data. However, it was intended for government use only and not for public use. Above all, in the beginning, the computer was a very large and heavy machine.

Computer Performance

The computer works in a three-step cycle namely input, process, and output. Also, the computer follows this cycle throughout the process that was asked to be performed. In simple terms, the process can be described this way. The information we enter into the computer is the input method, the CPU function that performs the process and the output that the computer produces.

Components and types of computers

A simple computer basically contains a CPU, monitor, mouse, and keyboard. Also, there are hundreds of other computer components that can be attached to it. These other components include printer, laser pen, scanner, etc.

Computers are divided into many different types such as supercomputers, mainframes, computers (desktops), PDAs, laptops, etc. A cell phone is also a type of computer because it fulfills all the requirements of being a computer.

Computer Use in Various Fields

As computer use increased it became necessary in almost all sectors to use computers in their work. Also, make it easier to work and sort things out. Below we list some of the key fields that use computers in their daily work.

Medical Field

They use computers to diagnose diseases, perform tests, and find cures for deadly diseases. Also, they are able to find solutions to many diseases because of computers.

Research

Whether it is scientific research, space research or any social research computers it helps them all. And, thanks to them, we are able to keep an eye on nature, space, and society. Astronomical experiments have helped us to study galaxies. While scientific research has helped us find resources and various other useful resources from around the world.

Protection

In any country, his defense is of paramount importance to the safety and security of his people. Also, the computer in this field helps national security agencies to detect potential threats in the future. Above all the defense industry use them to keep an eye on our enemy.

Its use depends entirely on you. Otherwise, the day will come when human civilization will not be able to survive without computers as we rely heavily on it. So far it has been the great discovery of humanity that has helped save thousands and millions of lives.

Also, Computer is one of the greatest invention of man. The present age students under any circumstances would never imagine even in their dreams that there were a time when there were no computers.

So much we have propelled that now every data is only a click away and in your grasp, day in and day out. This headway was conceivable just with the presentation of a little gadget called the Computer.

In order to make the students aware about the history of computer and make them learn more about them, we have prepared essays for students. These essays shall throw light on the advancements that the world has seen in the field of computers and shall prove helpful for the preparation of examinations as well.
