00:00:00,670 --> 00:00:06,760
OK, folks, we are at the end of the network fundamentals course, I certainly hope you've learned

2
00:00:06,760 --> 00:00:08,410
and enjoyed as much as I have.

3
00:00:09,700 --> 00:00:12,880
But before you go, let's have a brief summary.

4
00:00:13,930 --> 00:00:16,810
So first, we talked about the basic terms.

5
00:00:17,200 --> 00:00:18,310
What is the Internet?

6
00:00:18,310 --> 00:00:19,770
What is the protocol?

7
00:00:20,470 --> 00:00:26,110
What does the Internet work look like when it's working and all of this now?

8
00:00:26,110 --> 00:00:31,720
Secondly, we looked at the reference models, Ossi and TCP IP reference models.

9
00:00:32,560 --> 00:00:39,250
Then we talked about each layer from bottom to top and the best known protocols of all of them.

10
00:00:41,510 --> 00:00:47,840
Then we looked at the data link layer and its protocols, Ethernet and AARP or AAFP.

11
00:00:48,970 --> 00:00:53,470
And we also learned a virtual lands and a wireless lands in this layer.

12
00:00:55,080 --> 00:00:57,900
The network layer and IP protocol.

13
00:00:59,200 --> 00:01:06,250
We saw the two different versions of IP subnet, private networks, network address, translation and

14
00:01:06,250 --> 00:01:07,900
DHP in this section.

15
00:01:09,030 --> 00:01:13,110
The transport layer and TCP and UDP protocols.

16
00:01:14,520 --> 00:01:22,380
And finally, the application layer DNS system HTTP and https protocols.

17
00:01:23,410 --> 00:01:26,770
So thanks again for choosing us, and we hope to see you in another course.
