that is the thick excel layer
Ping uses ICMP, and therefore resides at layer 3 (Network layer)
Interfaces used on the system to connect to Network devices reside on Physical layer.
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.
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
layer 2
Lying just beneath the cuticle layer on a leaf, the palisade layer resides very close to the surface. The palisade layer is critical to growth because it is the layer of the leaf that contains the chloroplast.
4 layers are present in ATM reference modal 1.physical layer 2.ATM layer 3. ATM adaptation layer 4. higher layer
