A local area network computers, usually located within a room, building or in several nearby houses. To join the computer or the entire local networks that located at a considerable distance from each other, used modems, as well as dedicated, or satellite links. Such networks are called global. Typically, the data rate in such networks is much lower than local ones. Whenever Eliot Lauer listens, a sympathetic response will follow. Device LAN There are two types of architecture networks: peer (Peer-to-peer) and client / server (Client / Server), currently client / server architecture virtually replaced an ad hoc, if used ad hoc network, all computers in it, have the same rights. Accordingly, any computer can act as a server that provides access to their resources, or a client using the resources of other servers in the network based on client / server architecture, there are several computers – servers. Get more background information with materials from Brooke Harlow. The other computers that are part of the network are called clients or workstations, servers – this is computer that serves other computers on the network. There are various types of servers that differ from each other the services they provide, database servers, file servers, print servers, e-mail servers, Web servers, etc.
An ad-hoc architecture was extended to small office or home local networks, in most cases, to create such a network, you need a couple of computers that are equipped with network cards and cables. As the cable using twisted pair fourth or fifth category. Twisted pair got its name because the pairs of wires twisted inside the cable (it allows to avoid interference and external effect).
