Identify the topology from the given options, which is a hierarchical topology in which there are multiple branches and each branch can have one or more basic topologies and usually connects multiple LANs.

Correct option is B

The Tree topology is a hierarchical topology that consists of multiple branches. Each branch can have one or more basic topologies, such as star or bus, and it typically connects multiple LANs (Local Area Networks). This structure resembles a tree with a root node and various sub-nodes (branches), where each branch can represent a different segment of the network. Tree topology is ideal for larger networks with multiple departments or segments that need to be connected.
Important Key Points:
1. Hierarchical Structure: Tree topology uses a parent-child relationship between devices or groups of devices, with a central root node branching out into multiple child nodes.
2. Combination of Topologies: It can combine other topologies, such as star or bus, in each of the branches.
3. Scalability: It allows for easy expansion by adding new branches, making it suitable for large networks.
4. LAN Connectivity: Tree topology often connects multiple LANs, making it a preferred choice for campus networks or multi-floor buildings.
5. Fault Tolerance: The hierarchical nature provides a degree of fault tolerance, as issues in one branch may not affect the others.
Knowledge Booster:
· Option (a): Bus topology uses a single central cable (the bus) to which all devices are connected. It does not follow a hierarchical structure and lacks the scalability and branching nature of tree topology.
· Option (c): Star topology connects all devices to a central hub or switch. While it provides a central connection point, it does not inherently support hierarchical or branching structures like tree topology.
· Option (d): Mesh topology involves every device being connected to every other device. This results in high redundancy but does not fit the hierarchical or branching nature of tree topology, making it more complex and less scalable for connecting multiple LANs.
