Bus network information

What is a bus network

A 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. Each node is shown as a sphere, the bus appears as a heavy horizontal line, and connections to the bus appear as vertical lines.

Disadvantages

Disadvantages

  • 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
  • Not meant to be used as a stand-alone solution in a large building
  • It is slow when more devices are added into the network
  • If a main cable is damaged then network will fail or be split into two networks

Advantages

Advantages

  • Easy to connect a computer or peripheral to a linear bus
  • Requires less cable length than a star topology
  • It works well for small networks.
