computer is one of the greatest inventions of modern science. It is an electronic machine that can store, process, and display data according to the instructions given to it. The word “computer” comes from the English word “compute,” which means “to calculate.” In the beginning, computers were mainly used for mathematical calculations, but now they are used in almost every field of life.
A computer has two main parts: hardware and software. Hardware includes all the physical parts of a computer that we can see and touch, such as the monitor, keyboard, mouse, and CPU. Software, on the other hand, is a set of programs and instructions that tell the computer how to perform specific tasks. Both hardware and software are necessary for a computer to work properly.
The history of computers is quite interesting. The first mechanical computer was designed by Charles Babbage in the 19th century. Over time, computers have gone through many stages of development. Earlier computers were large, slow, and expensive, but today’s computers are small, fast, and affordable. Modern laptops, tablets, and even smartphones are all examples of compact and powerful computers.
