Local Area Networking systems - Essay ExampleStair & Reynolds suggest that usually, local area network is wired into office buildings, factories, school buildings etc and are built around personal computers (PC). When a PC is connected to a local area network, a network interface card (NIC) is required which is placed in a computers expansion slot to allow it to communicate with the network. A wire or connector from the network is then plugged directly into NIC. (Stair & Reynolds, 2001, p. 138)In order to lay and configure a LAN setup in a school, first of all the topology should have to be selected. Out of the three topologies, i.e. ring, bus and headliner, star topology is the most feasible one, as due to the failure of a computer or a segment of wire or a node, the new(prenominal) network nodes would not be affected at all. For star topology the basic hardware required for connectivity are as followsFor a smaller LAN with a maximum of 10 computers Hub works fine but for a larg er LAN a agitate gives better efficiency compared to a hub. The causation is that the hub broadcast the data packet to every node, hence all other nodes except the destination node thereby ignoring the broadcasted data packet where as the switch store the MAC addresses of each node and would send the data packet only to the destination node.Further more in a larger LAN setup, if the distance between two switches or between switch and a terminal (computer) is more than 100 meters than we have to use a repea
