In computing, a port in Windows (and other operating systems) refers to a logical connection point that software programs use to communicate with each other or with external devices over a network or the internet. Ports allow different programs and devices to send and receive data to and from each other, helping to facilitate the flow of information. Each port is assigned a unique number, known as a port number, which helps to identify and direct traffic to the appropriate destination. Examples of commonly used ports in Windows include TCP, UDP, COM, LPT, USB, and Bluetooth ports.
