What is Port (computer networking)

Image result for What is Port (computer networking)
In the internet protocol suite, a port is an endpoint of communication in an operating system.
While the term is also used for female connectors on hardware devices (see computer port), in software it is a logical construct that identifies a specific process or a type of network service.
A port is always associated with an IP address of a host and the protocol type of the communication, and thus completes the destination or origination network address of a communication session.
A port is identified for each address and protocol by a 16-bit number, commonly known as the port number. For example, an address may be 'protocol: TCP, IP address: 1.2.3.4, port number: 80', which may be written 1.2.3.4:80 when the protocol is known from context.
Specific port numbers are often used to identify specific services.
