Explanation

IP addresses and routers both operate at Layer 3 (the Network layer) of the OSI model. IP addresses are logical addresses used at Layer 3 for routing packets between networks. Routers are Layer 3 devices that use IP addresses to forward packets between different networks. Hubs operate at Layer 1 (Physical) - they simply repeat electrical signals. Switches operate at Layer 2 (Data Link) by using MAC addresses to forward frames within a network. MAC addresses are Layer 2 hardware addresses used for local network communication within a single network segment.
