Which device connects multiple computers to a single network?

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

Answer: (C)

The chosen answer is a switch, which functions by connecting multiple devices within a local area network (LAN) and directing data packets between them. Unlike a hub, which simply broadcasts data to all connected devices, a switch operates more intelligently by filtering and sending information only to the specific device that needs it. This improves efficiency and network performance by minimizing unnecessary traffic. Additionally, switches can handle more complex networking tasks, such as managing Ethernet frames and supporting multiple data transmission channels. This capability allows for greater scalability in larger network environments where many devices need to interact seamlessly. In contrast, although routers also connect devices, their primary function is to route data between different networks rather than just within a single network. A modem, on the other hand, connects a home or office network to the Internet, serving a different purpose from that of a switch. Thus, a switch is the most suitable choice for connecting multiple computers to a single network efficiently.
