Your question is not specific enough to elicit an answer because errors can happen in any of the layers.
Open system interconnection is the general networking model. Open system interconnection model is introduced by ISO . Physical layer is the first layer of OSI model.Data link layer is the second layer of OSI model. Data Link Layer, this layer is where we actually assign meaning to the electrical signals in the network.
Networking layer of the OSI model
The OSI model is a general model for networking . It has seven layer in total and each layer have some responsibilities. The layer that determines the communication mode is physical layer.
it comes in the first layer, or popularly known as the physical layer. must not be confused to be in datalink 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).
Router works in Network Layer of OSI model
that layer
application layer
First layer of the OSI model covers the cabling and electrical signaling. The first layer of OSI model is the physical layer. The physical layer also decides the transmission mode and physical media.
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
The Internet model consists of 4 layers: Application layer, Transport layer, Network layer, and Link layer. Each layer is responsible for specific functions in the process of sending data over the Internet.
The transport layer in an OSI model is the layer that moves information or data between the network layer and the session layer. The Open Systems Interconnection model is a way of visualizing the processes that happen in communication and networking.
