After reading this paper the reader should know how each of the terms works in a computer. The reader will also have knowledge of each terms advantages and disadvantages.

Mesh Topology

A mesh network has a very simple concept. Because of the simple concept a mesh network has fewer chances of breaking down the network. Many possible combinations of routes and hops data transferred can take one way or another to the destination. All of the nodes connect to each other, which makes mesh topology a complete network. The data is automatically configured to take the shortest route. An advantage would be that mesh topology provides redundant paths between devices. A disadvantage is that a mesh topology requires more cables. Complication of implementation is another disadvantage.

Bus Topology

With a bus topology all node on the network shares a common bus, whereas, the nodes also shares communication. Because the bus topology is sharing with others, only one device when transmitting is done one at a time. The bus topology connects each of the nodes to a single line. The single line is typically a coax cable. A protocol determines which computer is to transmit. Advantages to the bus topology if there is a failure at one station the failure will not affect others. Suited for temporary networks of the bus topology setup must be done in a hurry. Bus topologies are also easy to implement and extend. A bus topology does have its disadvantages. Bus topology requires a network to detect when two nodes are transmitting at the same time. If there is a heavy traffic rate a bus topology does not cope well. The bus topology is difficult to troubleshoot. The bus topology has a limit to the number of stations and the cable length. A break in the cable causes the entire network to disable and cost to maintenance could...
