Network Topologies

Network Topologies

Bus- is the most simple of the networks. There are two different types of buses, Linear and Distributed. Distributed bus network nodes of the network are connected to a common transmission, which has more than two endpoints that are created by adding branches to the transmission medium.

Linear bus network nodes of the network are connected to a common transmission, which has exactly two endpoints, which all of the devices the networks are connected to a common central cable called a bus, backbone, or trunk. Major advantages of the bus topology are that it is a relatively inexpensive and it is easy to add new devices to the network by simply connecting them to the bus. If the main cable fails, the entire network will shut down. When it shuts down it could be difficult to determine why the cable failed. Bus topology is low cost and is widely used in business.

Ring- each node is connected to two other nodes creating a ring and with the first and last being connected to each other, forming a ring. This topology is the more reliable than the bus and star. If one of the nodes in the ring topology fails the network administrator can route data around the failed node. These types of networks are expensive and somewhat difficult to install. There is also a Dual-ring network topology this happens when the network is connected to two other nodes in the network and with the first
