BIOS
Basic Input-Output System. A computer pro-
gram and set of default parameters stored in
ROM which tests and operates your computer
when you turn it on until it loads your installed
operating system from disk. Information from
the BIOS is transferred to the installed operat-
ing system to provide it with information on
the configuration and status of the hardware.
Bit
An abbreviation for binary digit. A single piece of
information which is either a one (1) or a zero (0).
bps
An abbreviation for bits per second. Used to
describe data transfer rates.
Boot
To start-up a computer and load its operating
system from disk, ROM or other storage media
into RAM.
Bus
An electrical circuit which passes data
between the CPU and the sub-assemblies
inside your computer.
Byte
8 bits of parallel binary information.
Cache Memory
A block of memory built into the micro-
processor which is much faster to access than
your system RAM and used in specially struc-
tured ways to make your overall data handling
time faster.
CardBus
A faster, 32-bit version of the PC Card interface
which offers performance similar to the 32-bit
PCI architecture.
CD-ROM
Compact disc read only memory. This is a form
of digital data storage which is read optically
with a laser rather than a magnetic head. A
typical CD-ROM can contain about 600MB of
data and is not subject to heads crashing into
the surface and destroying the data when there
is a failure nor to wear from reading.
CHS Translation
Cylinder, head and sector translation.
Conversion of hard drive access addressing to
the cylinder, head and sector form. The termi-
nology is historical left from the days when data
was stored on a series of cylindrical drums. The
head designates the reading device, similar to
the head on a cassette recorder only mounted
on a movable arm. Another addressing
method is LBA.
CMOS RAM
Complementary metal oxide semiconductor
random access memory. This is a technology for
manufacturing random access memory which
requires very low levels of power to operate.
COM Port
Abbreviation for communication port.
This is your serial interface connection.
