such as video, drives, and networks.
PCI Express
— A modification to the PCI interface that boosts the data transfer rate
between the processor and the devices attached to it. PCI Express can transfer data at
speeds from 250 MB/sec to 4 GB/sec. If the PCI Express chip set and the device are
capable of different speeds, they will operate at the slower speed.
PCMCIA
— Personal Computer Memory Card International Association — The
organization that establishes standards for PC Cards.
PIO
— programmed input/output — A method of transferring data between two
devices through the processor as part of the data path.
pixel
— A single point on a display screen. Pixels are arranged in rows and columns to
create an image. A video resolution, such as 800 x 600, is expressed as the number of
pixels across by the number of pixels up and down.

POST
— power-on self-test — Diagnostics programs, loaded automatically by the
BIOS, that perform basic tests on the major computer components, such as memory,
hard drives, and video. If no problems are detected during POST, the computer
continues the start-up.
processor
— A computer chip that interprets and executes program instructions.
Sometimes the processor is referred to as the CPU (central processing unit).
PS/2
— personal system/2 — A type of connector for attaching a PS/2-compatible
