Definition of "Network" |
A system of transmission and distribution lines cross-connected and operated to permit multiple power supply to any principal point on it. / A combination of electrical components. In a parallel circuit it is composed of two or more branches. Network Topologies A Network is any connection of two or more computers that enables them to communicate. Networks may include transmission devices, servers, cables, routers and satellites. The phone network is the total infrastructure for transmitting phone messages. / A system of transmission and distribution lines cross connected and operated to permit multiple power supply to any principal point on it. / An electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, voltage sources, current sources and switches. An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Linear electrical networks, a special type consisting only of sources voltage or current, linear lumped elements are resistors, capacitors, inductors, and linear distributed elements are transmission lines, have the property that signals are linearly superimposable. / In information technology, a network is a series of points or nodes interconnected by communication paths. Network can interconnect with other networks and contain subnetwork.The most common topology or general configurations of networks include the bus, star, token ring, and mesh topologies. Networks can also be characterized in terms of spatial distance as local area network (LANs), metropolitan area network (MANs), and wide area network (WANs).A given network can also be characterized by the type of data transmission technology in use on it (for example, a TCP/IP or Systems Network Architecture network), by whether it carries voice, data, or both kinds of signals, by who can use the network (public or private), by the usual nature of its connections (dial-up or switched, dedicated or nonswitched, or virtual connections), and by the types of physical links (for example, optical fiber, coaxial cable, and Unshielded Twisted Pair). Large telephone network and network using their infrastructure (such as the Internet) have sharing and exchange arrangements with other companies so that larger network are created. / Subscription television system that sends programs in scrambled form to TV sets equipped with decoders. / combination of interconnected components, circuits or systems. |
