A network bridge connects multiple network segments at the data link layer (Layer 2) of the OSI model.
In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).
If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).If you mean the OSI reference model, that's layer 1 (physical).
Physical layer which is the first layer in OSI reference model is responsible for signal encoding and decoding.
layer 2
There are seven type of OSI reference model:-Layer 7: The application layer Layer 6: The presentation layer Layer 5: The session layer Layer 4: The transport layer Layer 3: The network layerLayer 2: The data-link layer Layer 1: The physical layer
network layer
The top layer of the OSI model; Application
Network Layer
network
Repeaters operate at the physical layer of the OSI model.
ATM consists of 3 layers AAL (adoption layer) ATM layer (similar to DataLink layer) and Physical layer. AAL layer has no equivalent in the OSI model.
4 layers are present in ATM reference modal 1.physical layer 2.ATM layer 3. ATM adaptation layer 4. higher layer
