Serial Port

A Serial Port is a PC connection used for peripherals such as modems, mice and gaming devices. A serial port is also known as a COM port, or if you want to be technical an RS-232 port. They come in two kinds, a 9 or 25 pin connection and they are the slowest port on a computer (they can only transmit data one bit at a time) and for the main part have been replaced by the fastest USB ports.
