Explanation

A bridge operates at Layer 2 (the Data Link layer) of the OSI model and forwards frames based on MAC (Media Access Control) addresses. It connects homogeneous (same-type) network segments and learns MAC addresses by inspecting frames, building a forwarding table. Traffic destined for a MAC address on the same segment is filtered (not forwarded), while traffic destined for a MAC on the other segment is forwarded - reducing collision domains. Routers use IP (Layer 3) addresses, gateways translate between dissimilar protocols/architectures, and firewalls focus on security policy enforcement rather than simple MAC-based forwarding.
