backup—A copy of a file, usually on a removable disk, kept in case the
original file is lost or damaged.
basic input/output system (BIOS)—See BIOS.
baud rate—The speed at which a communication device, such as a
printer or modem, transmits information. Baud rate is the number of
signal changes per second (not necessarily the same as bits per
second). See also bits per second.
BIOS (basic input/output system)—Basic instructions, stored in read-
only memory (ROM), containing the information the computer needs
in order to check hardware and load the operating system when you
start up the computer.
bit—Short for "binary digit." A bit is the smallest unit of information
used by a computer. A group of eight bits is a byte. See also byte.
bits per second (bps)—A way of measuring the speed at which
information is passed between two devices. The basic measure used in
modem communications, bps is similar, but not identical, to the baud
rate. See also baud rate.
boot—To start the computer. This term originates from the bootstrap
program (as in "pulling itself up by its bootstraps"), a program that
loads and initializes the operating system. See also reboot.
boot disk—See system disk.
boot priority (startup sequence)—The order in which the computer
accesses its disk drives to locate the startup files. Under the default
startup sequence, the computer looks for the startup files in the diskette
drive before checking the hard disk.
bus—An electrical circuit that connects the central processing unit
(CPU) with other parts of the computer, such as the video adapter, disk
drives, and ports. It is the pathway through which data flows from one
device to another. See also bus speed, frontside bus.
bus speed—The speed at which the central processing unit (CPU)
communicates with the other parts of the computer.
byte—A sequence of eight bits. A byte is the smallest addressable unit of
data. See also bit, gigabyte, kilobyte, megabyte.
