# What Is The Number Of Cable Links Required For A Mesh,ring,bus And Star Topology?

The number of links required for any of the following topologies depends on how many computers will be using the system. Let's just say, in this instance, there are four computers using the system. The number of cable links required for a mesh topology is 6, a ring topology is 4, a bus topology is 3, and a star topology is 4.

• Mesh Topology
This network connection allows all the computers to be linked to the internet. This specific topology uses the most cables, however it is the system that is less likely to fail or experience any faults. Due to the fact that the computers have about 3 cables running out of them, if a failure does occur in one cable, it won't completely lose the network.

• Ring Topology
The ring topology is self-explanatory in the sense that the cables are managed in a ring shape. The cables connect to each computer which allows the signals to go through each device. It is not likely that it will obtain any problems during its function. However, if there are any problems with the cables then the whole system will go down and no computers will be able to connect to the network.

• Bus topology
With the bus topology, information sent through is not renewed or resent from device to device. Due to this, the computers are safe from crashing down if one of the network fails. However, a problem with this is that when there is an issue with the cables, it cannot be easily identified.

• Star topology
This is the only system that uses a central hub to connect to all the computers. The cables provided will travel from each computer to the hub and the network will be powered from the central device.

Links required for mesh topology = n(n-1)/2
Links required for ring topology = n-1
Links required for star topology = n
