an operating environment in the form of several virtual disks whose entire
capacity approximates that of the underlying disk or array.
PCB
Printed Circuit Board, also called cards or adapters, a thin plate consisting of
chips and other electronic components.
PCI
Peripheral Component Interconnect, a standardized architecture that
provides a high-speed data path between peripherals and the CPU. PCI is a
high-performance, backplane interface, expansion slot architecture found on
PC, Macintosh, and UNIX workstations. PCI cards are portable across
hardware platforms with the help of various software drivers.
PCI Hot Plug
A feature that allows for the printed circuit board (PCB) to be replaced
without powering down the entire system—an essential feature in newer
PCI-based PCs. Mylex DAC960PG, DAC960PJ, AcceleRAID, and
eXtremeRAID products are all PCI Hot Plug compatible. See also Hot Plug.
Peripheral
Any computer device that is not part of the essential computer, but is situated
