port
1. <networking> 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 the same 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 1700, divided into
well-known ports and registered ports.
2. <operating system, programming> 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. <language> An imperative language descended from Zed
from Waterloo Microsystems (now Hayes Canada) ca. 1979.

System].
