A port, or interface, that can be used for serial communication, in which only 1 bit is transmitted at a time.

Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port).
