A parallel port, on the other hand, is an interface through which the communication between a computer and
                 its peripheral device takes place in a parallel manner i.e., data is transferred in or out parallelly or simultaneously
                 using more than one communication line or wire. Printer port is an example of a parallel port.
                 Video Ports

                 Video Graphics Array (VGA): It is found in computers, projectors, video cards and many TVs. The connector
                 is called DE-15. It is a D-shaped sub connector consisting of 15 pins in 3 rows.









                 With the increase in the use of digital video, VGA ports are gradually being replaced by HDMI and Display
                 Ports. Some laptops have extra on-board VGA ports to connect to external monitors or projectors.

                 Digital Video Interface (DVI): It is a high-speed digital interface between a computer (CPU) and a display
                 device like a monitor. It was developed to replace the VGA technology. DVI-I, DVI-D  and DVI-A are the
                 common types of DVI connectors.











                 Display Port: It is a digital display interface with multiple channels for audio and other forms of data. It can
                 replace VGA and DVI ports as the main interface between a CPU and monitor. The latest version of Display
                 Port is 1.3 which supports resolutions up to 7680 X 4320.











                  igh Definition Media  nter ace   DM  : It is a digital interface that helps us to connect High Definition
                 (HD)  and  Ultra  High  Definition  (UHD)  devices  like  computer  monitors,  HDT s,  Blu-Ray  players,  gaming
                 consoles, High Definition cameras, etc.












                 Universal Serial Bus (USB)

                 The USB port is used to transfer data. It acts as an interface for peripherals and a power supplier for devices
                 connected to it. USB replaced serial ports, parallel ports, game ports and power chargers for portable devices.
                 There are various kinds of USB ports: Type A, Type B, Mini USB, Micro USB and Type C.
