In a network where every computer is connected to a central hub or switch, and failure of one cable affects only that computer but failure of the central device brings down the whole network, the topology is:
This is a star topology. Every node connects to a central hub or switch, so one cable failure isolates only that node, but the central device is a single point of failure for the entire network.
- ABus topology
- BRing topology
- CStar topologyCorrect
- DMesh topology
Explanation
In a star topology each node connects to a central device, so a single cable fault isolates only that node, while the central device is the single point of failure. In a bus, a break in the backbone cable affects many nodes; in a ring, a break can disrupt circulation of data. Mesh has multiple redundant links with no central dependency.
