Which of the following is best described as similar to a hub?

A repeater is best described as similar to a hub because its primary function is to regenerate and amplify signals in a network. Like a hub, a repeater operates at the physical layer of the OSI model, meaning it deals with raw bit transmission rather than interpreting any data packets. Both devices, therefore, serve to extend the distance over which a signal can effectively travel, allowing devices on a network to communicate over longer distances without degradation of the signal.

While switches, bridges, and routers perform more complex tasks—such as filtering, routing, and making decisions based on the data they handle—they operate at higher layers of the OSI model and can manage data intelligently, unlike a repeater or a hub.
