|
a 32/64-bit expansion slot designed by intel specifically for video that runs at 66 MHz and yields a throughput of at least 254 MBps. later versions (2x, 4x, 8x) give substantially higher throughput.
|
accelerated graphics port (agp)
|
|
|
a silver or pink bag that is designed to protect sensitive components by ensuring that any static charge collects on the outside of the bag rather then the components inside.
|
anti-static bag

|
|
a specially designed device to bleed electrical charges away safely. it uses a 1- megohmrestior to bleed the charge away slowly and protect computer hardware.
|
anti-static strap

|
classically the software routines burned onto the system ROM of a PC. more commonly seen as any software that directly controls a particular piece of hardware. a set of programs encoded in read-only memory (ROM) on computers. these programs handle startup operations and low level control of hardware such as dick drives, the keyboard, and monitor.
|
BIOS (basic input/output services)
|
|
|
electronic chips that handle all of the low-level functions of a pc, which in the original pc were handled by close to 30 different chips. they usually consist of 1, 2 or 3 separate chips embedded into a motherboard to handle all of these functions.
