A computer system includes a computer, peripheral devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware” refers to components called peripheral devices that expand the computer’s input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool.

Computers become even more effective when connected to other computers in a network so users can share information.
