This sounds like a homework question.....hmmmm.
Anyway- if there's a break in a bus topology, the nodes that are downstream from the break are cut-off from the rest of the network.
In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.
One of the nodes ... the one at the end of the broken cable ... goes out of service,
but with a properly designed hub, the other nodes are unaffected.
Communication stops completely.
Bus Topology.
Bus topology is used on a LAN, or a Local Area Network. It is the cable to which the nodes connect, and it is also known as a backbone.
A bus topology needs a trunk cable, which is a high speed central cable to which all the nodes can be connected. If the trunk cable breaks down, however, the whole network comes to a halt.
The bus cable to which computers on the Ethernet is connected is called the trunk. If the trunk breaks, a bus topology is completely disrupted.
UTP cable would not usually be used in a bus topology. It is very common (even at that low speed) for a star.

Star topology is like the network is done by easily adding another network and the most common cable is used unshielded twisted pair cable. For the star topology purpose, Cat5 and Cat6 cable is used because it is an unshielded and shielded twisted pair cable.
Mesh topology- a cable at fault not affect others. Ring topology- a cable at fault, only affect side by side, If main cable at fault ,whole system shut down. Star topology- a cable at fault, others are not affected. If Hub at fault, whole system shut down. Bus topology- main cable at fault, system will shut down. a cable at fault,will not affect others.
A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
Bus
Bus topology is the most popular topology. Justify.
The advantage is in fault detection; in a bus topology any break in any wire segment would cause the entire LAN to fail. With a star topology, a break in any wire segment only affects the one client connected to the network.
