Bus Topology

Bus topology is a setup of a network where network devices, computers or nodes are directly linked to a single cable, or we can say with a common link. An RJ-45 network cable or coaxial cable is preferred to link them, depending on the type of system network card.

In a bus topology, we have another important term which is the station. Basically, a host on a bus network is known as a station. When it comes to the bus network, all the stations will accept all network traffic, and this traffic will have a similar transmission preference.

Important Pointers of Bus Topology

  • The bus topology is created efficiently, and every station is linked via a single cable called a backbone cable.
  • There are two conditions: First, the nodes are directly linked to the backbone cable, or they take the help of a drop cable to make a connection.
  • When it comes to the bus topology, the famous access technique is CSMA (Carrier Sense Multiple Access).

CSMA: It’s a type of media access control that handles data flow to guarantee data integrity.

Advantages of Bus Topology

  • It works excellently in a tiny network.
  • Bus topology is the most uncomplicated topology for linking computers linearly.
  • It demands a shorter cable length as compared to the star topology.
  • In the case of bus topology, nodes are directly linked to the cable; therefore, the starting cost of installation is quite low.

Disadvantages of Bus Topology

  • In the case of bus topology, it is very tough to determine the issues if the entire network goes down.
  • For large networks, it is not suitable.
  • We need terminators at both ends of the primary cable.
  • It is tough to troubleshoot particular device issues.
  • The network divides into two if the primary cable is harmed.
  • If we add new devices to the bus topology network, it would affect the network and slow down.
  • Though the concept of bus topology is pretty easy, it still demands a lot of cabling.
