Network Types

Local Area Ne iirk (local ara lucre) A local direct network is a sm al superstar network that connects computers and some other devices in express geographical bea such as phalanx post building, computer labs, school or closely positi iodind classify of buildings. It has limited size, typically spanning a few hundred meters and no to a greater extent than a mile. LAN is change the sharing of resources such has files or hardw ar devices that whitethorn be needed by six-fold pulmonary tuberculosisrs. LAN transmits data with some(prenominal) Megabits per seconds ( gigabyteMbps). The transmission medium is normally concentric or theatrical role optic cables. That can make many users as nose candy or even 1000 users. In typical LAN configuration, one computer is designated as the file server. It stores all of the packet that can be share by the computers attached to the network. Computers connected to the file server are called workstation. The workstation can b e slight powerful than the file server, and they may have additional bundle on their hard drive. every(prenominal) single computer in network called as node. apiece node in LAN are linked together with certain topology. LANs Topologies Bus Topology Networks employing a bus topology use a mutual corporeal connection for communication. That means the physical media is shared between stations. When one station transmits on the bus, all devices hear the transmission.

If more than than one device transmits at the same(p) time, the two transmissions will collide with separately other and twain transmissions will destroy each othe r. When two or more of these devices attemp! ts to access the network bus at the same time, virtually method must be apply to prevent a collision (CSMA/CD). Historically, bus networks used coaxial cable as their medium of transmission. Token Bus, Ethernet are common examples of bus topologies. Although well-nigh installations of Ethernet using coaxial cable even-tempered exist, all novel installations now use a hub and rung or friend topology. Ring Topology Ring topologies are similar to bus topologies, except they transmit in one...If you wishing to get a plentiful essay, order it on our website: BestEssayCheap.com
