Data Link Control
11.1
, 11-1 FRAMING
The data link layer needs to pack bits into frames, so
that each frame is distinguishable from another. Our
postal system practices a type of framing. The simple
act of inserting a letter into an envelope separates one
piece of information from another; the envelope serves
as the delimiter.
Topics discussed in this section:
Fixed-Size Framing
