1.0 Introduction The selection and utilization of the proper Network topologies and protocols is essential to maintain a functional and fail safe network from which the businesses work computers are able to operate. This report will review the appropriate and available protocols and topologies that can be utilized in CompuParts inc. 2.0 Topologies 2.1 What are Topologies? A networks topology in basics is the physical layout and logic behind the connection of elements (links, terminals, nodes, ect.). There are numerous amounts of network layouts, each one for different sizes and requirements. This report will look at five of the most efficient and viable layouts for CompuParts inc. 2.2 Linear Bus A linear bus network is the simplest of all the networks, in that all nodes are connected to a central cable with two end points. All data and information that is sent through this network is sent through this central cable and is sent to every node on the network. The advantage of this network topology is that only one cable needs to be purchased, apart from the connectors from node to cable, but a disadvantage is that all packets are sent to every node on the network. A variation of this network is the distributed linear bus, which has more than two endpoints, created by adding more braches to the main cable. All the endpoints must be ended with a terminator. 2.3 Star Network A star network is one in which all the nodes are connected to a central hub. This way (if the hub is an active hub, meaning it can store information), all packets are sent to the hub and then directed straight through to the receiving computer, and if the hub is a passive one, all packets are sent through the hub to every node on the network until it reaches the receiving node. The central device does not need to be a hub, but works far more
