What type of address does a switch primarily use to forward frames within a network?

A switch primarily uses MAC addresses to forward frames within a network. Each device connected to a switch has a unique MAC address, which is a hardware address that identifies the device at the data link layer (Layer 2) of the OSI model. When a switch receives a frame, it examines the destination MAC address to determine the appropriate port to which it should forward the frame. This process is known as MAC address learning and forwarding. The switch builds and maintains a MAC address table, mapping each MAC address to the corresponding port. As the switch learns which devices are connected to which ports, it can efficiently forward frames only to the intended recipient rather than broadcasting them to all ports, which enhances network efficiency and reduces unnecessary traffic. In contrast, while IP addresses are used for communication across networks at the network layer (Layer 3) and are important for routing packets between different networks, switches do not rely on them for frame forwarding. Broadcast and multicast addresses have specific roles in domain-wide communication but do not determine how a switch manages individual frames within local network communications.
