The document discusses different types of data link protocols including asynchronous and synchronous protocols as well as character-oriented and bit-oriented protocols. It provides figures illustrating examples of data link protocols such as XMODEM and how frames are structured in simple, multiblock, and multiframe transmissions. Control frames and byte stuffing techniques are also examined.
