What physical topology is used in a small network that connects multiple devices through a hub?

1. Point-to-point

2. Star

3. Mesh

4. Ring

The correct answer is: Star

In a small network that connects multiple devices through a hub, the topology used is classified as a star topology. In a star topology, all devices (such as computers, printers, and other networked devices) are connected to a central device, which in this case is the hub. This arrangement allows each device to communicate with one another through the hub, which facilitates the management of data transmission. The star topology is advantageous because it simplifies fault isolation; if one connection fails, the other devices on the network remain operational. Additionally, it's easier to add or remove devices without disrupting the entire network. This is distinct from other topologies like point-to-point, which connects only two devices directly, mesh, where each device is connected to many other devices for redundancy, and ring, where devices are connected in a circular fashion. Each of these alternatives has its own specific use cases and benefits, but in the scenario of connecting multiple devices through a single central hub, the star topology is the most appropriate choice.
