Q. Define layered network model?
- The OSI Reference Model is collection of seven layers every specifying particular network functions.
- The process of breaking up the functions or else tasks of networking into layers reduces complexity.
- Every layer provides a service to the layer above it in the protocol specification.
- Every layer communicates with the same layer's software or hardware on other computers.
- The lower 4 layers (network, transport, data link and physical -Layers 3, 4, 2, and 1) are concerned with the flow of data from end to end through the network.
- The upper top four layers of the OSI model (application and presentation and session-Layers 6, 7and 5) are orientated more toward services to the applications.
- Data is encapsulated with the essential protocol information as it moves down the layers before network transit.
