Explanation
A switch operates at Layer 2 and provides LAN segmentation by giving each port its own collision domain, which isolates traffic between devices. Because each port has a dedicated connection, devices can send and receive data simultaneously, enabling full-duplex communication. Hubs share bandwidth among all ports and only support half-duplex. Repeaters simply regenerate signals without segmentation. Modems convert signals between digital and analog and do not segment a LAN.
