PCI
Peripheral Component Interconnect - This is a high-performance, backplane
interface, expansion slot architecture that is found on PCs, Macintoshes, and
UNIX workstations. PCI is a standardized architecture that provides a high-
speed data path between peripherals and the CPU. PCI cards are portable
across hardware platforms with the help of various software drivers.
PCI Hot Plug
An essential feature in newer PCI-based PCs which allows for the printed
circuit board to be replaced without powering down the entire system. Mylex
DAC960PG, DAC960PJ, AcceleRAID and eXtremeRAID products all are
PCI Hot Plug compatible.
Peripheral
Any computer device that is not part of the essential computer (the
processor, memory, and data paths) but is situated relatively close by.
Platform
An underlying computer system on which application programs can run. A
platform consists of an operating system, the computer system's
coordinating program, and a microprocessor, the microchip in the computer
that performs logic operations and manages data movement in the computer.
Plug and Play
The ability to install peripheral cards or other devices without requiring
manual configuration by the user.
