They are sometimes referred to as Communication (COM) ports.
Are also D-shaped with 9 or 25 pins.
They are used primarily to connect devices such as serial Mice, external Modems, and sometimes Printers to the System unit. They can also be used for computer-to-computer connection.
The Serial port has 2 data lines, one for data in & the other for data out.
Transmission rates of Serial ports are slower than those of Parallel ports. This is because, Serial ports transmit data bit-by-bit. Therefore, they are used for devices that accept information 1 bit at a time (or for devices that are a bit slow).
