In contrast to audio and video transmission, the primary purpose of communications ports is to facilitate the movement of data. Dedicated audio/video ports, high-definition multimedia interface (HDMI), DisplayPort, and universal serial bus (USB) connections are the most prevalent types of connections used for audio and video applications.

Your computer and any connected devices may send and receive data using a communications port, which is a group of pins that allows for this. The control lines, ground (GND), receive (RX), transmit (TX), and others are all parts of these pins. In the process of sending data from your computer, the data is transformed into a stream of bits and then sent via the TX pin. Through its RX pin, the linked device is able to receive these bits and then interpret them in the appropriate manner.
