tcp-ip

=TCP/IP= TCP/IP the set of [|communications protocols] used for the [|Internet] and other similar networks. It is named from two of the most important protocols in it: the [|Transmission Control Protocol] (TCP) and the [|Internet Protocol] (IP), which were the first two networking protocols defined in this standard. Today's IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s, namely the [|Internet] and LANs ([|Local Area Networks]), which emerged in the mid- to late-1980s, together with the advent of the [|World Wide Web] in the early 1990s. The Internet Protocol Suite, like many protocol suites, may be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the [|upper layer protocols] based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on [|lower layer protocols] to translate data into forms that can eventually be physically transmitted.
