Quizplus · Accepted Answer

To exchange data between two host computers in different networks, we need a device that can handle the routing of data packets between them. This device must have knowledge of both networks and be able to route packets based on their destination IP address. A router is the only option listed that can perform this function, making it the best choice. Bridges, switches, hubs, and access points all operate at the data link layer and are used for connecting devices within a network, not between networks.
