Which topology is exemplified by computers connected to an Ethernet hub?

The correct answer is the star topology. In a star topology, all devices, such as computers and printers, are connected to a central device, which in this case is an Ethernet hub. The hub acts as a repeater for the transmission and receives information from the devices, directing the data to the appropriate recipient. This allows for easy management and troubleshooting of the network because if one connection fails, it does not affect the entire network; only the device connected to that specific port will be impacted.

In contrast, mesh topology features devices that are interconnected, creating multiple paths between them, which enhances redundancy. Bus topology involves nodes connected along a single cable; if the cable fails, the entire network can go down. Ring topology connects devices in a circular manner, where data travels in one direction, and if a single device or connection fails, it can disrupt the whole network as well. Thus, star topology is characterized by its reliance on a central hub for connection, making it the most appropriate choice in this scenario.
