Port

On computer and telecommunication devices, a port is generally a 
specific place for being physically connected to some other device, 
usually with a socket and plug of some kind.   Typically, a personal 
computer is provided with one or more serial ports and usually one 
parallel port.  The serial port supports sequential, one-bit-at-a-time
transmission to peripheral devices such as scanners; the parallel port 
supports multiple-bit-at-a-time transmission to devices such as 
printers.
