Explanation
A computer is an electronic machine that processes information. It can take input (like typing or clicking), store data, and give output (like showing results on a screen). People use computers for studying, working, entertainment, and communication. For example, a student uses a computer to write essays, play games, or search the internet. A business uses computers for calculations, data storage, or online meetings. Computers can be large (servers) or small (laptops, tablets, smartphones). They follow instructions called “programs” or “software” to perform tasks. A computer has parts like the monitor, keyboard, mouse, and internal hardware.
