Request For Comment. An Internet
standard. The name arose at a time when the documents were
regarded as proposals to be submitted to a then-nonexistent
but anticipated formal approval process of some sort. The
formal approval process never materialized.
RPC
Remote Procedure Call. Use of
IPC methods that attempt to create the illusion that the
processes exchanging them are running in the same address
space, so they can cheaply (a) share complex structures, and (b)
call each other like function libraries, ignoring latency and other
performance considerations. This illusion is notoriously
difficult to sustain.
