| | | | 5. NETWORK TOPOLOGY Network Topology is defined as the arrangement of interconnections of several elements within a computer system. Wired and wireless LANs naturally use different topologies, the most commonly used topologies for wired LANs are bus, ring, star, tree and mesh. “A computer network topology is the physical communication scheme used by connected devices”. (Mitchell 2011). 5.1 Bus Topology Bus Topology is a connection between the data terminals whereby a single network cable which serves as a shared communication medium is routed through areas where terminals are located and a connection (tap) made to each through an interface connector. Bus networks are extendable into interconnected set of buses…show more content…
Instead, it uses radio or light waves for transmission purposes. Wireless network gives the added value of being able to connect handheld devices and portable computers wirelessly. This is worth considering in a case where structure, office layout etc. changes frequently. There are two common wireless network connection types namely fixed wire replacement and ad hoc networks. Fixed wire replacement being a LAN adopting wireless connection where otherwise would have been a wired LAN due to constant layout changes or cost. Ad hoc network simply is a real and full wireless LAN with port-to-port connections. Fig 3.0 Some of the benefits of Wireless LAN are as follows: * Simplified implementation and Maintenance – Less expensive and useful in places with constraints for laying cabling. * Extended reach – Users are able to connect to the Network resources from any location within the Network AP (Access point) transmission range. * Increased mobility – Roaming benefits means users can move freely and are not restricted to particular sitting position or location as they can connect via a wireless enabled device like a phone or
