Local Area Network (LAN) for DesignIT‚ a Local Area Network (LAN) is a network of computers‚ and other network devices such as printers which exchange data‚ and are located under one roof. LAN networks are mostly used in small organizations or small businesses. The computers in a LAN communicate through protocols and share data such as files and emails. Every computer in a network is assigned a unique Internet Protocol (IP). When a computer communicates by sending a request to the LAN network‚ it is routed

questions‚ so be sure to state your assumptions. Assumptions 1. All college buildings‚ administration departments and residence halls are connected to a BN. 2. The relatively large colleges with 3 buildings have 3 separate LANs each. One LAN on each building. Each LAN is connected to the other through a router that is connected to the BN. 3. All other buildings are connected to the BN through a router. 4. Assuming one router supporting the BN. It will be assigned the IP address 128.100

LOCAL AREA NETWORK (LAN) 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

4. The Medium Access Sub Layer Broadcast channels [or multi-access channels] are a category of networks and the key issue is how to determine who gets to use the channel when there is competition for it. The protocols which define these factors belong to a sub layer of data link layer called the MAC(medium access control)sub layer. ALOHA: Norman Abramson devised a new and elegant method to solve the channel allocation problem called the “ALOHA” system which used ground-based Radio broad
