secure Web site A Web site that encrypts data to protect it from unauthorized use. When you purchase items over the Internet, you are asked to type your name, mailing address, e-mail address, and credit card information on an electronic form. Sending information to a secure Web site is comparable to giving it over the telephone when you order from a catalog. (But never send your social security number over the Internet. Criminals can steal your identity with your social security number.)

See also encrypt.

serial port A small connector on the back of the computer (or keyboard) for plugging in a thin cable attached to a serial device, such as a mouse. Serial devices transfer data, one bit at a time, through a data wire. The serial cable has two wires for bidirectional communication (sending and receiving information simultaneously). See also digital and parallel port.
