"(n.) (1) An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards. Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices.
Almost all personal computers come with a serial RS-232C port or RS-422 port for connecting a modem or mouse and a parallel port for connecting a printer. On PCs, the parallel port is a Centronics interface that uses a 25-pin connector. SCSI (Small Computer System Interface) ports support higher transmission speeds than do conventional ports and enable you to attach up to seven devices to the same port.
(2) In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic."
"A device, resembling a plug-in of sorts, found on the back of a PC. It allows access in and out of the computer for cables. The ports can be used to connect all types of devices. For example, many users connect a printer to a computer through the parallel port and connect a mouse through a serial port. Also, to port is to convert software from one environment to another, such as from Windows 95 to Unix."
