PorTs

Port is an external connecting socket on the outside the computer. This is a pathway into and out of the computer. A port lets users plug in outside peripherals, such as monitors, scanners and printers.

• Serial Ports

Serial port was created as an interface between data terminal equipment and data-communications equipment. It processes data sequentially, as a series of bits, and is used to connect equipment such as a modem or mouse to the computer.



• Parallel Ports

The parallel port processes several data bits in parallel and is used to connect peripherals such as computer printers and optical scanners to the computer. The parallel port is faster, but the serial port is cheaper and requires less power.
