A computer is an electronic machine which helps to make our work easy and faster. A computer is a machine that takes input from the user and gives the output. The father of computers is Charles Babbage because in 1833 he invented all the parts that are used for the modern computer. But it was only 120 years later that the modern computer was invented. And Konrad Zuse was the first modern computer in the world in 1936 and named Z1. In 1939 he created Z2 as the first electro-mechanical computer in the world.
A computer is very useful to everyone especially for office work because everything in the office is done by a computer. If they don’t use computers they can’t work. And if we have computers we can do complex things in a simple manner. We can communicate, play games, play music, write, and save. Also, we can use the computer for entertainment. Now we are able to read and study from home because of the computer. A computer has many parts like CPU, Monitor, Keyboard, etc. Many people say that the CPU is the computer's mind. There are different types of computer-based generation and they are the first generation, second generation, third generations, and fourth generations. The first generation was based on Vacuum Tube, the second generation was based on transistors, the third generation was based on Integrated circuits(IC). The fourth-generation was developed from 1971; it is still being developed up to the present date. This generation was based on microprocessors. Currently, we are using a more advanced level that has been developed up to the 8th generation.
