Network layer
Repeaters operate at the physical layer of the OSI model.
generally layer 4, but SOCKS operates at layer 5, which allows it to work well with applications
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
FTP operates in application layer of ISO OSI layered model.
TCP operates at Layer 4 which is Transport of the OSI Model!
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.
Transciever works on the Physical Layer(Layer 1) of the OSI because its basically a repeater or a MAU\ Multi Station Access Unit
If you mean the MAC address, that's a layer-2 concept.
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.
No. A digital subscriber line (DSL) operates at layer 2 or the Data-link layer.
Physical layer devices would be a hub or a repeater to connect multiple Ethernet segments together.
