Telecommunications engineer working to maintain London's phone service during World War 2, in 1942. Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance.
Network terminal nodes are at the edges of the network. In the context of telecommunications, a terminal is a device which ends a telecommunications link and is the point at which a signal enters or leaves a network. Examples of terminal equipment include telephones, fax machines, computer terminals, printers and workstations.
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals.
The protocols in use today in this layer for the Internet all originated in the development of TCP/IP. In the OSI model the transport layer is often referred to as Layer 4, or L4, [2] while numbered layers are not used in TCP/IP. The best-known transport protocol of the Internet protocol suite is the Transmission Control Protocol (TCP).
Communication system An electronic communications system using electronic signals. A communications system or communication system is a collection of individual telecommunications networks systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole.
In telecommunications, the term terminal equipment has the following meanings: Communications equipment at either end of a communications link , used to permit the stations involved to accomplish the mission for which the link was established.
Typical delays for modern communication transmission lines vary from 3.33 ns/m to 5 ns/m. When sending power down a transmission line, it is usually desirable that as much power as possible will be absorbed by the load and as little as possible will be reflected back to the source.
Successful block transfer is the transfer of a correct, nonduplicate, user information block between the source user and intended destination user. Successful block transfer occurs when the last bit of the transferred block crosses the functional interface between the telecommunications system and the intended destination user.
