An asynchronous port on the computer used to connect a serial device to the computer and capable of transmitting one bit at a time. Serial ports are usually identified on IBM compatible computers as COM (communications) ports. For example, a mouse might be connected to COM1 and a modem to COM2.

Where is the serial port on a computer?
The serial port is found on the back of the computer and is part of the motherboard.
NoteWith the introduction of USB, FireWire, and other faster solutions serial ports are rarely used when compared to how often they've been used in the past. Also, many new computers and laptops no longer have a serial port.
