00:00:00,700 --> 00:00:04,510
‫OK, folks, we are at the end of the network fundamentals course.

2
00:00:04,960 --> 00:00:08,380
‫I certainly hope you've learned and enjoyed as much as I have.

3
00:00:09,700 --> 00:00:12,850
‫But before you go, let's have a brief summary.

4
00:00:13,930 --> 00:00:18,270
‫So first, we talked about the basic terms what is the internet?

5
00:00:18,280 --> 00:00:19,750
‫What is the protocol?

6
00:00:20,470 --> 00:00:25,240
‫What does the internet work look like when it's working and all of this?

7
00:00:25,930 --> 00:00:31,690
‫And secondly, we looked at the reference models OSAI and TCP IP reference models.

8
00:00:32,560 --> 00:00:39,220
‫Then we talked about each layer from bottom to top and the best known protocols of all of them.

9
00:00:41,510 --> 00:00:47,780
‫Then we looked at the data link layer and its protocols, Ethernet and ERP or ARB.

10
00:00:48,970 --> 00:00:53,500
‫And we also learned a virtual LANs and the wireless lands in this layer.

11
00:00:55,080 --> 00:00:57,900
‫The network layer and IP protocol.

12
00:00:59,170 --> 00:01:06,220
‫We saw the two different versions of IP Subnet Private Networks, Network Address, Translation and

13
00:01:06,220 --> 00:01:07,900
‫DHP in this section.

14
00:01:09,030 --> 00:01:13,070
‫The transport layer and TCP and UDP protocols.

15
00:01:14,520 --> 00:01:22,380
‫And finally, the application layer, DNS system, HTTP and HTTPS protocols.
