none of the above
Network layer
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!
Which? Where are the Options?WAN Technologies operate & involve Layer1, Layer2 & Layer3 of OSI Model. Example of WAN Technology Protocols are Frame Relay, ATM & X.25 protocols.
If you mean the MAC address, that's a layer-2 concept.
Layer 3 deals with logical addresses and operates with IP addresses.
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.
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
It operates on the data link layer of the OSI model (level 2). The switch creates a separate collision domain for each port. Although some switches operate on level 3 of the model and are called multi-layer switches.
