layer 3 layer 3 Switch/ Bridges / Hubs works at layer 2 as they utilizes MAC address to communicate. However i aggree above stated answer as there are some layer three switches that work at Layer3 i.e. Network Layer. Dhruv
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Layer 1 - the physical layer
Layer 4 : The Transport Layer
Layer 7: The Application Layer
physical layer Layer 1
The OSI model attempts to explain the way in which computers communicate. The layers are as follows: Application Layer Data Layer Transmission Layer Computer Layer Keyboard Layer Electric Layer Hacking Layer
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Ethernet switch fits on osi physical layer
network layer
hub work at physical layer of osi model
2
Layer 1 - the physical layer
Layer 2.
Layer 2 , Data Link Layer
Layer 4 : The Transport Layer
Layer 7: The Application Layer
physical layer Layer 1
