The IP(Internet Protocol) address enables network communication on a specific device, and the port numbers specify the particular service to target on those devices. For example, all Hypertext Transfer Protocol (HTTP) messages go to port 80. Mostly each port is reserved for serving a specific protocol.

TCP (Transmission Control Protocol) portsĪ number is assigned to each port, so the ports are standardized and adopted across all the network-connected devices.

There are two types of network ports on each computer. Each network request contains the port, IP address, and the network protocol to complete the request's destination network address. The incoming packet's headers define which port it should be forwarded.

The email traffic lands on a different port (port 25), and web traffic lands on a different (port 80) even though both reach the computer over the same network connection. Ports facilitate computers to differentiate among different kinds of traffic.

We can recognize it as a logical construct used to specify a network service or a particular function at the software level. Each port is associated with a specific service or process. Ports are software-based and managed by the computer's operating system. It is the virtual point where the network connection starts and ends. Port is a term used in computer networking.
