bandwidth
Bandwidth is often used to express the rate of data transfer in
an I/O channel. This usage assumes that a wide bandwidth
may contain a high frequency, which can accommodate a high
rate of data transfer.
baud rate
The speed at which data is transmitted over a data line. Baud
rates are measured in bits per second.
binary
A number system that uses two digits: 0 and 1. They are
represented in system circuitry by two voltage levels, and
programs are executed in binary form.
bit
Binary digit. The smallest unit of data in a binary notation
system, designated as 0 or 1.
boot
Short for bootstrap. Loading an operating system into memory is
called booting.
bootstrap
See boot.
bus
A group of signals that consists of many transmission lines or
wires. A bus interconnects computer system components to
provide communications paths for addresses, data, and control
information.
byte
Eight contiguous bits starting on an addressable byte boundary.
The bits are numbered right to left, 0 through 7. It is the
memory size required to store one ASCII character.
cache
See cache memory.
