The Data Link Layer
Data link layer
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
i believe (not quite sure) that it is at the application layer (layer 1)
Layer 1 - the physical layer
Physical layer which is the first layer in OSI reference model is responsible for signal encoding and decoding.
layer 2
presentation layer
hi
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
Data link layer
Networking layer of the OSI model
Packet switching is considered part of layer 3 of the OSI model.Packet switching is considered part of layer 3 of the OSI model.Packet switching is considered part of layer 3 of the OSI model.Packet switching is considered part of layer 3 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).
hub work at physical layer of osi model
The top layer of the OSI model; Application
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
