RAM ROM

The smallest element of a display, a dot of color on your display screen. The more pixels per area the clearer your image will appear.

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.

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.

Reset

The act of reloading the operating system.

A reset erases all information stored in RAM.

Restart

See Reset.

Resume

To proceed after interruption. In your Computer this refers to returning to active operation after having been in one of the suspension states.

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.
