COMPUTERS

There are four main types of computers: super computers, mainframe computers, minicomputers, and microcomputers. Super computers are the most powerful and are used for specialized tasks like space exploration by NASA. Mainframe computers are very expensive and used by large organizations to run business operations. Minicomputers are used by small businesses and are less powerful than mainframes. Microcomputers include devices like desktops, laptops, tablets, and smartphones and are the most widely used.
