Describe the premise of the OSI Reference Model.
What will be an ideal response?
The premise of the OSI Reference Model is that information created by the user or client is translated and encoded through the various layers, from the top level at the Application layer to the bottom level at the Physical layer, where it is transmitted across a net-work, to a receiver, where it is broken down by the receiver's protocol stack in reverse order. Each layer provides a header with specific information on the function of that layer, then passes the data and header to the next-lower level, where it becomes the data payload for that layer.
