LAYERS

When it comes to communications, all of these standard organizations have one primary function: the creation of standards that can be combined with others to create a working network. One concern is that these organizations be able to recommend solutions that are both flexible and complete, even though no single standards entity has complete control over the entire process from top to bottom. The way this is done is to divide the communications process up into a number of functional layers.

Data communication networks rely on layered protocols. In brief, processes running on a system and the communication ports that send and receive network bits are logically connected by a series of layers, each performing one major function of the networking task.
