![]() These two groups of ports are serial ports and parallel ports. In a laptop or computer, ports can be divided into two groups depending upon how the port allows the communications. Most of the vendors follow the same common standardization for making computers and their ports. But in general, this shape doesn't differ from one vendor to another. Port comes in a wide variety of shapes such as round(PS/2), square( RJ 45), rectangular (FireWire, USB, etc), trapezoidal(DB-25 printer port, DB-9 serial port). The main purpose of this port is to allow one hardware component to be plugged in another so that they can communicate with each other. Technically they are basically slots on your motherboard.Ĭomputer Port is also called a communication port because they are responsible for communication between the computer and peripheral devices. So, in general, we can say computer/laptop port is nothing but just an interface or point of connection between peripheral devices(input/output devices) to the computer. In a computer system, we called this connector the port. For communicating any two-piece of hardware you may require some interface to connect them.
