Bus topology

In this article we will discuss Bus topology, will make brief discussion on Bus topology, In last article we discuss about Point-to-point.

bus topology is a topology for a Local Area Network (LAN) in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a “backbone”. If the backbone is broken, the entire segment fails.

bus network is an arrangement in a local area network (LAN) in which each node (workstation or other device) is connected to a main cable or link called the bus. The illustration shows a bus network with five nodes. A bus network is a network topology in which nodes are directly connected to a common linear half-duplex link called a bus.

Common examples are star ring networks and star bus networks. Tree topology is one specific example of a star bus network. Consider, for example, a multistory office building. The network could consist of a bus running vertically through the building to provide network access to each floor.

Entire network shuts down if there is a break in the main cable. Terminators are required at both ends of the backbone cable. Difficult to identify the problem if the entire network shuts down.
