Quizplus · Accepted Answer

Port numbers are the well-known range of numbers that are reserved to identify specific service types provided by host computers. They allow multiple services to run on a single host computer and are used by the transport layer protocols, such as TCP and UDP, to identify the destination service on a host computer. IP addresses identify the network and the device on the network, sockets are the endpoint of a two-way communication link between two programs over a network, and URLs specify how to access a resource on the internet.
