Detailed explanation-1: -Answer: A. In a mesh topology, all devices are connected directly to every other device on the network. If one link fails, there is always another available. It is the most fault-tolerant network topology.
Detailed explanation-2: -In star topology, the central site plays an important role; if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection. For a star topology, it may happen that two nodes might be closed to each other; however, they will have to communicate via central node.
Detailed explanation-3: -Mesh topology: In this, each device has a dedicated point to point link to every other device. Dedicated means that a link carries traffic only between two devices it connects. It is the most reliable topology.
Detailed explanation-4: -Advantages of Mesh Topology The failure of a single node does not cause the entire network to fail as there are alternate paths for data transmission. It can handle heavy traffic, as there are dedicated paths between any two network nodes.
