POST
Power On Self Test. A program which is part of
the BIOS which checks the configuration and
operating condition of your hardware whenever
power is applied to your Computer. Status and
error messages may be displayed before the oper-
ating system is loaded. If the self test detects fail-
ures that are so serious that operation can not
continue, the operating system will not be loaded.
Program
An integrated set of coded commands to your
computers telling your hardware what to do
and how and when to do it.
PS/2
An IBM series of personal computers which
established a number of standards for con-
necting external devices such as keyboards
and monitors.
RAM
Random Access Memory. A hardware compo-
nent of your computer that holds binary infor-
mation (both program and data) as long as it
has the proper power applied to it.
RAM Module
A printed circuit card with memory and associ-
ated circuitry which allows the user to add
additional memory to the computer without
special tools.

Computer this refers to returning to active
operation after having been in one of the

ROM
Read Only Memory. A form of memory in
which information is stored by physically
altering the material. Data stored in this way
can not be changed by your Computer and
does not require power to maintain it.
SDRAM
Synchronous Dynamic Random Access Memory.
Serial Port
A connection to another device through which
data is transferred one bit at a time on a single
wire with any other wires only for control of
the device not for transfer of data.
Shadow RAM
A technique of copying data or applications
stored in ROM (Read Only Memory) into RAM
(Random Access Memory) for access during
actual operation. RAM is much faster to access
than ROM, however ROM contents are not lost
when power is removed. Shadowing allows
permanently stored information to be
rapidly accessed.
