00:00:01,080 --> 00:00:06,960
In this video, we're going to discuss point to point protocols and point to point one connections or

2
00:00:06,960 --> 00:00:08,520
wide area networks.

3
00:00:08,910 --> 00:00:15,300
The two encapsulation that we're going to concentrate on in this section are point to point protocol

4
00:00:15,330 --> 00:00:20,710
or PGP and High Level Data Link Control or HDL-C.

5
00:00:21,090 --> 00:00:27,930
These are Layer two encapsulation lines that could be used on point to point serial connections which

6
00:00:27,930 --> 00:00:32,070
connect sites across disparate geographical areas.

7
00:00:33,010 --> 00:00:39,340
As an example, you may have a head office site in one part of the country or world and a branch or

8
00:00:39,340 --> 00:00:43,510
multiple branch offices in other parts of the country or world.
