Which device type can primarily be used to connect computers in a star topology?

1. Router

2. Hub

3. Switch

4. Access Point

The correct answer is: Hub

In a star topology, devices are connected to a central point, typically allowing for efficient communication and easy troubleshooting. A hub serves as that central connection point, enabling multiple devices to connect to it. When a computer sends data to another computer on the network, the hub receives that data and broadcasts it to all connected devices. While hubs have become less common due to the advancement of technology, they are historically significant examples of devices used in a star topology. In contrast, while switches and routers also connect devices, they operate at different levels and have more advanced functions than a basic hub. A switch, for example, can intelligently direct data only to the device intended to receive it, which improves network efficiency. Access points, on the other hand, facilitate wireless connections and are not directly related to the cable-based connections typically found in star topologies.
