What device is used to connect multiple networks together?

• A. Access Point
• B. Router
• C. Switch
• D. Hub

Answer: (B)

A router is designed to connect multiple networks together and facilitate communication between them. It operates at the network layer of the OSI model and is responsible for determining the best path for data to travel between different networks. Routers manage traffic within a network by forwarding data packets based on their destination IP addresses. Access points serve a different purpose by allowing wireless devices to connect to a wired network, but they do not connect multiple networks themselves. Switches operate at the data link layer and are used primarily to connect devices within the same network, directing data to specific devices on the same local area network. Hubs, which are largely outdated, simply connect multiple devices in a network without any intelligence in directing traffic, operating at a very basic level of broadcasting data to all connected devices rather than selectively routing it between distinct networks. This functionality of the router to interface and route between multiple networks is what makes it the appropriate choice for this question.
