Explanation

A switch maintains a MAC address table (also called a CAM table) that maps MAC addresses to physical ports. When a frame arrives, the switch looks up the destination MAC address in this table and forwards the frame only to the correct port. A hub broadcasts to all ports without any address logic. A router uses IP addresses (Layer 3), not MAC addresses (Layer 2). A bridge also uses MAC addresses but is a simpler, older device that typically connects only two segments, while a switch is essentially a multi-port bridge with full MAC table management.
