hardware.

BIOS
An abbreviation for "Basic Input/Output System". Core software for computer systems with
essential routines for controlling input and output processes on hardware components, for
performing tests after system start, and for loading the operating system. Although BIOS is used
to configure a system's performance, the user does not usually come into contact with it.
-bit
Binary digit > binary position, binary character, smallest discrete unit of information. A bit can
have the value 0 or 1.
Bit rate

Bootstrap loader
A program that automatically runs when the computer is switched on or restarted. After some
basic hardware tests have been carried out, the bootstrap loader starts a larger loader and hands
over control to it, which in turn boots the operating system. The bootstrap loader is typically found
in ROM on the computer.

capacity. The following units are the commonly used units of progression: KB, MB, GB.
