00:00:00,930 --> 00:00:04,350
‫And finally, we're in the application layer.

2
00:00:05,180 --> 00:00:10,730
‫Now, if you remember, I mentioned before for the ease of use, the last three layers session layer,

3
00:00:10,730 --> 00:00:16,700
‫presentation layer and application layer are thought of together as the application layer.

4
00:00:17,270 --> 00:00:22,430
‫As you know, these three layers are already a single layer in the TCP IP reference model.

5
00:00:23,940 --> 00:00:29,850
‫So the application layer contains the communications protocols and interface methods used in process

6
00:00:30,030 --> 00:00:34,350
‫to process communications across an internet protocol computer network.

7
00:00:35,280 --> 00:00:41,310
‫The application layer only standardizes communication and depends upon the underlying transport layer

8
00:00:41,310 --> 00:00:47,400
‫protocols to establish host to host data transfer channels and manage the data exchange in a client

9
00:00:47,400 --> 00:00:49,740
‫server or peer to peer networking model.

10
00:00:50,820 --> 00:00:54,480
‫So let's have a look at some important protocols of the application layer.
