What device sends data packets using logical addresses?

• A. Repeater
• B. Router
• C. Hub
• D. Switch

Answer: (B)

A router is the device responsible for sending data packets using logical addresses. It operates at the network layer of the OSI model, where it identifies packets based on their destination IP addresses. Routers use these logical addresses to make decisions about the best paths for sending data across complex networks, such as the internet. In contrast, other devices such as repeaters, hubs, and switches operate using different principles. A repeater functions merely to regenerate signals to extend transmission distances and does not interpret any addressing. A hub operates at the physical layer and simply broadcasts data to all connected devices without any consideration of addressing. A switch, while it does use MAC addresses for data forwarding decisions at the data link layer, does not operate with logical addresses like IP addresses. Therefore, the router is clearly the correct choice because of its specific role in managing and directing data packets based on logical addressing.
