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.

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. The term “boot” originates from 

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

files in the diskette drive before checking the hard disk.
