Bus Topology

A linear bus topology consists of a main run of cable with a terminator at each end. All nodes (file server, workstations and peripherals) are connected to the linear cable. Ethernet and LocalTalk networks can use a linear bus topology. All devices are connected to a central cable called the bus or backbone.

1. Advantages of a Bus Topology
   
   • Easy to connect a computer or peripheral to a linear bus.
   • Requires less cable length than a star topology.

2. Disadvantages of a Bus Topology
   • Entire network shuts down if there is a break in the main cable.
   • Terminators are required at both ends of the backbone cable.
   • Different to identify the problem if the entire network shuts down.
   • Not meant to be used as a stand-alone solution in a large building.

3. Example of Bus Topology
   • ARCnet (Token Bus)
   • Ethernet (10Base2).
