scroll To gradually move information across the screen when a document or Web page is too long or too wide to view all at once. Scroll bars are located along the right side and across the bottom of a window. When scroll arrows are present at the ends of the bars, you know that some information is off the screen. Click on one

of the arrows to scroll the information into view.

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 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 digital. See also parallel port.
