Network - Protocol, Communication

A communication protocol, or set of guidelines, is used to regulate how two or more endpoints communicate with each other in any legal combination. Communication protocols can be defined at any of several layers in a network layer model. The number and definition of the layers depend on the communications models being used. In a network, both workstations and servers need to support communication protocols. In most local-area networks (LANs), the server must be able to support protocols at several layers. Some servers support multiple protocol suites so that the server may support more than one communication protocol at each of several layers.
