Layered mannequin permits to work only with info wanted. We will deal with one layer with out information how the other layers work. For example, if we run an utility program, as an example text editor, we do not concern how this program was written and what programming language was used. We could know the way it was written, but it isn’t essential for us while we are utilizing it. Layered models allows us to grasp, build and use complicated system. With out abstraction it might be far harder.
