The external peripheral devices are connected with the mother board of the computer system through special interface called ports.
There are mainly five types of ports used to plugin external devices directly or through cables in order to use them as a part of the computer system. They are :-
(1) VGA port -
VGA (Video Graphics Array) port is used to connect video output devices like monitor or projector. This type is mainly used to transfer analog video signals from PC to video device. In the latest PC's these ports are replaced by by more reliable and faster HDMI and DVI ports.
(2) Paralleled port -
These ports are used to connect devices which sends multiple bits of data at one time. Mainly, it is used for connecting printers and other devices with high bandwidth.
(3) PS2 port -
This type of port is round in shape with six pinholes in it. This is generally used in IBM computers for connecting keyboard and mouse. In the latest PCs this technology has been replaced by USB technology.
(4) USB port -
USB (Universal Serial Bus) is the latest technology which transfers the data as well as provide power to the connected devices. This is a versatile port which can be used for connecting almost all types of devices.
(5) Serial port -
It is used to connect devices like mouse, modem etc as in these data is transferred serially bit by bit ,that is, one bit at a time. These are also known as COM ports.
