Port numbers are mainly used in TCP and UDP based networks, with an available range of 65,535 for assigning port numbers. Although an application can change its port number, some commonly used Internet/network services are allocated with global port numbers such as Port Number 80 for HTTP, 23...
A port is a virtual numbered address that’s used as a communication endpoint by transport layer protocols like UDP (user diagram protocol) or TCP (transmission control protocol). Network ports direct traffic to the right places — i.e., they help the devices involved identify which service is...
