Which device can be used to connect multiple network devices and manage traffic?

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

Answer: (B)

A switch is designed specifically to connect multiple network devices and manage traffic between them. It operates on the data link layer of the OSI model, making decisions based on MAC addresses to forward data only to the appropriate device within the local area network (LAN). This selective forwarding of frames helps reduce unnecessary traffic, improving overall network efficiency and performance. Unlike routers, which direct traffic between different networks or subnets by using IP addresses, switches work within the same network. Their primary role is to create a shared network, allowing devices like computers, printers, and servers to communicate with one another seamlessly. While a modem connects a network to the internet, and an access point allows wireless devices to connect to the wired network, those functions do not entail managing traffic between multiple devices in the way that a switch does. Thus, the switch is the most suitable answer for connecting multiple network devices and managing the traffic on that network.
