In this video, we're going to discuss point to point protocols and point to point one connections or
wide area networks.
The two encapsulation that we're going to concentrate on in this section are point to point protocol
or PGP and High Level Data Link Control or HDL-C.
These are Layer two encapsulation lines that could be used on point to point serial connections which
connect sites across disparate geographical areas.
As an example, you may have a head office site in one part of the country or world and a branch or
multiple branch offices in other parts of the country or world.
