What topology uses a central switch or hub to connect network nodes?

Star topology is characterized by its use of a central hub or switch to connect various network nodes. In this arrangement, all nodes, such as computers and devices, are independently connected to the hub. This structure allows for efficient data management, as the hub facilitates communication between nodes, and it can also help isolate problems since the failure of one node does not necessarily affect the others. The central switch or hub acts as a point of control, directing data to its intended destination, which helps in managing network traffic and improving overall performance.

In contrast, the other topologies function differently; mesh topology involves a direct connection between each node, allowing for multiple pathways for data but without a central hub. Bus topology connects all devices to a single communication line, which can lead to data collisions and is less efficient in terms of management. Ring topology connects nodes in a circular fashion, where data travels in one direction, which can create issues if any one of the nodes fails. Each of these alternatives provides unique benefits and drawbacks, but the star topology’s central hub feature makes it distinct.
