Which device is responsible for connecting multiple devices within a local area network (LAN)?

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

Answer: (C)

The device responsible for connecting multiple devices within a local area network (LAN) is a switch. A switch operates at the data link layer (Layer 2) of the OSI model and serves to receive incoming data packets and redirect them to their destination on the local network. It does this by using MAC addresses to identify the devices connected to its ports. In a typical LAN scenario, when one device sends data to another, the switch intelligently forwards that data only to the intended recipient, rather than broadcasting it to all connected devices. This ensures efficient transmission and helps to minimize unnecessary network traffic. By managing the data flow between devices, a switch enhances the overall performance of the network by reducing collisions and improving bandwidth utilization. While other devices like a router and an access point play important roles in networking, they serve different functions. A router connects different networks and provides the capability for data to be routed between them, and an access point allows wireless devices to connect to a wired network. A modem connects to the internet service provider and translates between digital and analog signals. Thus, in the context of connecting multiple devices within a LAN, a switch is the most appropriate choice.
