Which device is used to connect multiple devices on a network?

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

Answer: (B)

A switch is used to connect multiple devices on a network by receiving data packets from one device and forwarding them to the appropriate destination device on the network. Unlike a hub, which broadcasts data to all connected devices, a switch intelligently directs the data only to the specific device that requires it, improving efficiency and reducing network congestion. This makes switches ideal for local area networks (LANs), as they can manage traffic effectively among multiple devices, such as computers, printers, and servers. While routers, hubs, and modems serve important roles in networking, their primary functions differ from that of a switch. A router connects different networks together and routes data between them, allowing communication between various networks. A hub connects multiple devices in a network but lacks the intelligence of a switch, leading to less efficient communication. A modem, on the other hand, modulates and demodulates signals for connecting to the Internet and isn’t primarily focused on connecting multiple devices within a local network. In summary, a switch is specifically designed to facilitate communication among multiple devices in a network, making it the correct choice for this question.
