Byte asynchronous: Lacking regular time relationship. As applied to computer communications, asynchronous refers to the method of transmitting data that does not require a steady stream of bits to be transmitted at regular time intervals. AUTOEXEC.BAT: A batch file that executes a series of MS-DOS commands and programs each time you start the computer. B backup: A duplicate copy of files kept as a spare in case the original is destroyed. batch file: A file that can be executed from the system prompt containing a sequence of operating system commands or executable files. See also AUTOEXEC.BAT. binary: The base two number system composed of zeros and ones (off or on), used by most digital computers. The right most digit of a binary number has a value of 1, the next a value of 2, then 4, 8, 16, and so on. For example, the binary number 101 has a value of 5. See also ASCII. BIOS: Basic Input Output System. The firmware that controls data flow within the computer. See also firmware. bit: Derived from ģbinary digit,ī the basic unit of information used by the computer. It is either zero or one. Eight bits is one byte. See also byte. Bluetooth: A short-range radio technology designed to simplify wireless communication among computers, communication devices and the Internet. board: A circuit board. An internal card containing electronic components, called chips, which perform a specific function or increase the capabilities of the system. boot: Short for bootstrap. A program that starts or restarts the computer. The program reads instructions from a storage device into the computer's memory. bps: Bits per second. Typically used to describe the data transmission speed of a modem. buffer: The portion of the computer's memory where data is temporarily stored. Buffers often compensate for differences in the rate of flow from one device to another. bus: An interface for transmission of signals, data or electric power. byte: The representation of a single character. A sequence of eight bits treated as a single unit; also the smallest addressable unit within the system. Glossary-3
