BIOS - This stands for Basic Input Output System. BIOS controls the real-time clock and disk drives as well as the computer's peripheral equipment. bit - This is a binary data digit, either 1 or 0. 1 or 0 represents a single unit of data. boot - This means to turn on the power switch and load the operating system (DOS) into the computer so that it is ready to accept software applications. bus - This is a set of lines that transmit signals/information between the components within the computer. If the I/O channel is 32-bit, this means the data travels at least twice as fast as data on a 16-bit data bus. byte - A group of data units forming a single unit of data. There are eight bits in a single byte. clock (processing) speed - This measurement, usually given in MHz (megahertz) tells how fast the microprocessor in your computer handles data. The higher the number, the faster your computer. CPU - Central Processing Unit. Also known as a microprocessor. This chip processes all the instructions in the computer. computer - An electronic device that can receive, store and transmit data, and process arithmetic or logic operations. cursor - The blinking, moving spot of light that marks the active place on the monitor. 2 Chapter 7: Glossary

Glossary
BIOS
—
This
stands
for
Basic
Input
Output
System.
BIOS
con-
trols
the
real-time
clock
and
disk
drives
as
well
as
the
computer’s
peripheral
equipment.
bit
—
This
is
a
binary
data
digit,
either
1
or
0. 1
or
0
represents
a
single
unit
of
data.
boot
—
This
means
to
turn
on
the
power
switch
and
load
the
operating
system
(DOS)
into
the
computer
so
that
it
is
ready
to
accept
software
applications.
bus
—
This
is
a
set
of
lines
that
transmit
signals/information
be-
tween
the
components
within
the
computer.
If
the
I/O
channel
is
32-bit,
this
means
the
data
travels
at
least
twice
as
fast
as
data
on
a
16-bit
data
bus.
—
A
group
of
data
units
forming
a
single
unit
of
data.
There
are
eight
bits
in
a
single
byte.
clock
(processing)
speed
—
This
measurement,
usually
given
in
MHz
(megahertz)
tells
how
fast
the
microprocessor
in
your
computer
hand-
les
data.
The
higher
the
number,
the
faster
your
com-
puter.
CPU
—
Central
Processing
Unit.
Also
known
as
a
microproces-
sor.
This
chip
processes
all
the
instructions
in
the
com-
puter.
computer
—
An
electronic
device
that
can
receive,
store
and
transmit
data,
and
process
arithmetic
or
logic
operations.
cursor
—
The
blinking,
moving
spot
of
light
that
marks
the
active
place
on
the
monitor.
