occupies. Also see card shelf and logical slots.
PIA - peripheral interface adapter
PIC - personal information carrier (Army)
PIC - Personal Intelligent Communicator
PIC - priority interrupt controller
PIC - programmable interconnect component
PIC - Primary Interexchange Carrier. This is your default "1+" carrier
used for interLATA calls. In some areas you may have two PICs,
one for interLATA calls, and one for intraLATA long distance calls
(in which case it stands for Primary Intraexchange Carrier). In
some areas intraLATA long distance calls are still handled by your
RBOC, in others you now have a choice.

Plesiochronous - A condition in a synchronized digital network
where communicating devices are each synchronized to a
different timing source of the same accuracy and stability. Two
signals are plesiochronous if their corresponding significant
instants occur at nominally the same rate, but not necessarily in
the same phase, with any variation in rate constrained within
specified limits.
