Word Origin & History

port
"harbor," O.E. port "harbor, haven," reinforced by O.Fr. port, both O.E. and O.Fr. from L. portus "port, harbor," originally "entrance, passage," from PIE *prtu- "a going, a passage," from base *per- "to lead, pass over" (cf. Skt. parayati "carries over;" Gk. poros "journey, passage, way," peirein "to
pierce, run through;" L. porta "gate, door," portare "passage," peritus "experienced;" Avestan peretush "passage, ford, bridge;" Armenian hordan "go forward;" Welsh rhyd "ford;" O.C.S. pariti "fly;" O.E. faran "to go, journey," O.N. fjörðr "inlet, estuary"). Meaning "left side of a ship" is attested from 1543, from notion of "the side facing the harbor" (when a ship is docked). It replaced larboard in common usage to avoid confusion with starboard (q.v.); officially so by Admiralty order of 1844 and U.S. Navy Department notice of 1846. Fig. sense "place of refuge" is attested from 1426; phrase any port in a storm first recorded 1749.

port
"gateway," O.E., from O.Fr. porte "gate, entrance," from L. porta "gate, door," from PIE base *per- (see port (1)). Specific meaning "porthole, opening in the side of a ship" is attested from 1243.

port
"bearing, mien," c.1369, from O.Fr. port, from porter "to carry," from L. portare (see port (1)).

port
"sweet dark-red wine," 1691, shortened from Oporto, city in northwest Portugal from which the wine was originally shipped, from O Porto "the port."

port definition


1. A logical channel or channel endpoint in a communications system. The Transmission Control Protocol and User Datagram Protocol transport layer protocols used on Ethernet use port numbers to distinguish between (demultiplex) different logical channels on the same network interface on a computer.
Each application program has a unique port number associated with it, defined in /etc/services or the Network Information Service "services" database. Some protocols, e.g. telnet and HTTP (which is actually a special form of telnet) have default ports specified as above but can use other ports as well.
Some port numbers are defined in RFC 3232 (which replaces RFC 1700). Ports are now divided into: "Well Known" or "Privileged", and "Ephemeral" or "Unprivileged" (comprising "Registered", "Dynamic", "Private").

2. To translate or modify software to run on a different platform, or the results of doing so. The portability of the software determines how easy it is to port.
3. An imperative language descended from Zed from Waterloo Microsystems (now Hayes Canada) ca. 1979.
