Layer 3 i.e, network layer of the OSI model is used to IP addressing.
IP addresses are used primarily by layer 3 (network layer) of the OSI model for routine purposes.
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).
No. Hub works only on first layer. On second layer only swithc/bridge works on second layer of OSI model.
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
Router works in Network Layer of OSI model
ftp i.e file transfer protocol,used to transfer a file from node to node FTP works at OSI layer 7, the Application layer
