How Data is Placed in Frames

Simple timing gaps between frames cannot be used as all hardware devices (as part of the Physical Layer) run at slightly different speeds; resulting in skewing if time is relied upon.

A first attempt at a solution involves counting the size of a frame and placing this count in the data link header - blah!

This naive solution highlights problems with synchronization - assuming the receiver can detect a problem, how much of the arriving bit stream should be skipped to find the next frame?
