Which OSI layer defines the functions of logical network-wide addressing and routing?

The OSI model stands for the Open Systems Interconnection model. This involves the communication system needed for a computer to function and communicate to other systems. There are seven layers in the OSI model.

These layers include the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and the application layer. The layer below a layer supports that layer above. Each layer though serves a specific purpose and function.

For example, the first layer which is the physical layer defines the functions of logical network-wide addressing and routing. It is also known for transporting and receiving data from a piece of equipment. Usually the data that it receives is raw. The next link which is the data link layer allows for communication between two nodes.

Layer one of the OSI version is known as the tangible layer. The actual layer is the lowest layer in the seven-layer OSI model. The physical layer is made up of the underlying networking hardware transmission technologies of a matrix.

The physical layer designates the means of transmitting raw bits over a physical link connecting network modes OSI model is the open systems Interconnection model. It is a conceptual model that distinguishes and standardizes the communication functions of a telecommunications or computing system without regard to the internal technology.
