PS/2 port is now considered a legacy port as USB port has superseded it and very few of the modern motherboards include it as a legacy port. The pin out diagram of a PS/2 female connector is shown below.Įven though the pinout of both mouse and keyboard PS/2 ports are same, computers do not recognize the devise when connected to wrong port. PS/2 connectors are color coded as purple for keyboard and green for mouse. It was introduced with IBM’s Personal Systems/2 series of computers and hence the name PS/2 connector. PS/2 connector is developed by IBM for connecting mouse and keyboard.

The article gives a brief introduction to different types of ports along with their applications. Printer port is an example of parallel port. data is transferred in or out in parallel using more than one communication line or wire. The most common type of serial port is a D-Subminiature or a D-sub connector that carry RS-232 signals.Ī parallel port, on the other hand, is an interface through which the communication between a computer and its peripheral device is in a parallel manner i.e. They are Serial Ports and Parallel Ports.Ī serial port is an interface through which peripherals can be connected using a serial protocol which involves the transmission of data one bit at a time over a single communication line. In Computers, communication ports can be divided into two types based on the type or protocol used for communication.

Generally, the female end of the connector is referred to as a port and it usually sits on the motherboard.

The main function of a computer port is to act as a point of attachment, where the cable from the peripheral can be plugged in and allows data to flow from and to the device.Ī computer port is also called as a Communication Port as it is responsible for communication between the computer and its peripheral device. Some of the common peripherals are mouse, keyboard, monitor or display unit, printer, speaker, flash drive etc. A Computer Port is an interface or a point of connection between the computer and its peripheral devices.
