Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Routers support a variety of interface types. Switches typically support Ethernet interfaces.

Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.

Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
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.
Not really - they operate at the Data Link layer using the MAC address and therefore don't really segment a network. There are some managed switches that can do this or by using VLAN configurations, but ordinary switches will not really segment a LAN.
RIP is a IGP protocol that allows routers to advertise what they know about their routes to other routers. Since routers operate at the network layer (3), so does RIP.
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
