A serial port is used to connect external modems or an older computer mouse to the computer. It comes in two versions a 9-pin version (in the first picture below left) or a 25-pin model (second picture below right). The 9-pin is found on most newer computers.
Data travels over a serial port at 115 kilobits per second.
You can also use your serial port device on your USB port with this adapter: USB to Serial converter
