A computer is a machine which stores knowledge in its memory and does calculations on that knowledge. This knowledge is stored in symbols； it is called data. A computer usually has a monitor to show results. However， some computers can speak； these computers can be used for voice mail.
A computer frequently requires a boot device. The boot device contains the computer’s operating system and data. Computer programs can be installed onto a computer. Some people think that computers are less useful if they do not have access to the Internet. They think this because the Internet allows the computers to send and receive data and email across the world.
