Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.

router operates on Layer 3 and can be used as a switch
Routers operate at layer 3 of the OSI model while switches operate at layer 2. The data transmission form of a router is called a packet while in a switch, it is called a frame. Routers are mainly used in wide area networks while switches are used in local area networks.
Routers works in the network layer of the OSI model and choose the best ,shortest and optimized path to route the packets received from data link layer and requested by transport layer. BY Naghma
A router can be used to connect a LAN to the internet. A router works on the basis of an IP address. Every router has built-in operating system known as IOS. A router works on the network layer of the OS model and it routes the data towards the optimal path. Router uses the header information of the packets and forwarding table to define the best shortest possible path of the data.

The highest MAC address among the active interfaces of the network will be used. There will be no router ID until a loopback interface is configured. The highest IP address among the active FastEthernet interfaces that are running OSPF will be used. The highest IP address among the active interfaces will be used.
The highest IP address among the active interfaces will be used.
IP addresses are used primarily by layer 3 (network layer) of the OSI model for routine purposes.
The highest IP address among the active interfaces will be used.
Layer 3 i.e, network layer of the OSI model is used to IP addressing.
