P
Protocol
A set of rules and formats that determines
the communication behavior of network
entities at a given layer.
Proxy
A device or program that stands in
between a server (for example, a web site)
and a client (your browser), providing a
way to relieve some of the burden from
the server. For example, your service
provider may have a web proxy that keeps
copies of popular web pages; the proxy can
send you those pages instead of fetching
them directly from the web site, resulting
in faster page loading and less network
congestion.
R
RF
Abbreviation for Radio Frequency. Some
literature refers to coax as "RF cable" and
the connectors as "RF connectors."
RJ-11
A standard 2-conductor modular
connector, commonly used in North
America for connecting telephones.

connector, commonly used on Ethernet
cable. An RJ-45 connector looks like a wide
RJ-11 (telephone) connector.

32 characters long) that uniquely identifies

outlet to avoid disruptions.

may refer to this as the return path or
reverse path.
