A Local area network is a network that is confined to a relatively small area. It is general limited to a geographic area such; school, writing lab, building, office, or hall. A local area network’s linkages usually are accomplished with either telephone, coaxial, or fiber-optic cables. This network are privately own networks with and angle building or campus of up to a few kilometers in size. They are widely used to connect personal computers and work situation in company, or factories to share resources examples; printers and exchange information. LAN are distinguished from other kinds of networks by three characteristics; the size, their transmission technology, and their topology. Scope of the LAN is small, typically a single building or cluster of buildings. LAN are usually owned by the same organization that owns the attached device. There may be a substantial capital investment for both purchase an maintenance. Internal data rates of LANs are much greater than those of WANs. Traditionally, have provided data rates from about 1 to 20 Mbps. High- speed LANs are now being developed.
THE FACTORS THAT DISTINGUISH LOCAL AREA NETWORK FROM ALL OTHER KINDS NETWORKS
There are three various factors that distinguishes between LANs and other kind of networks, these factors are; THE SIZE THE TRANSMISSION TECHNOLOGY THE TOPOLOGY 1) SIZE
LANs often use a transmission technology consisting of a single cable to which all machines are attached, like the telephone company party lines once used in rural areas. Traditional LANs run at speeds of 10 to 100 Mbps, have low delays (tens of microseconds) and make very few errors. Newer LANs operate at higher speeds up to hundreds of megabits/sec.
2) TRANSMISSION
LANs often use a transmission technology consisting of a single cable to which all machines are attached, like the telephone company party lines once used in rural areas. Traditional LANs run at speeds of
