Peripheral Component Interconnect (PCI)
A local bus technology. SCSI host adapters, video cards, and other peripherals use PCI to send data directly to and receive
data directly from the CPU.
permanent virtual circuit (PVC)
A virtual circuit that provides service that is equivalent to a dedicated private line over a packet switching network
between two DTEs. PVC uses a fixed logical channel to maintain a permanent association between the DTEs. Once a
PVC is defined, no setup operation is required before data is sent, and no disconnect operation is required after data is
sent. ATM-CES uses PVCs as the basis for the permanent connections. See also circuit emulation service (CES)
