Training video course "How the Internet works"

Virtually any profession related to the web requires understanding the basics of the Internet - be it a web programmer, a tester or an SEO optimizer.



So we decided to release the course " How the Internet is arranged, " which will explain everything in a meaningful and intelligible way. The course is completely free!



As you know, the United States thought about the idea of ​​a network without a single center immediately after the USSR began to demonstrate the first successes in space - this was a prerequisite for the creation of the Internet. It's funny to note that the first data that the scientists tried to send was the word “LOGIN”, but the network fell off on the third symbol - not much has changed since then, right? =)

The course explains the three components of the Internet: the network of networks, the Internet Protocol and the World Wide Web. Then - domains, DNS system and domain hierarchy.



After all, even Bruce Willis knows that short domain names are the most convenient.









And the practice section explains how to ban / unban a site through the hosts file, how to use the ping utility (in different operating systems), and how to register your domain.



Here is one video from this course - we are especially proud of it because it’s about the TCP / IP protocol: for people who are just planning to start their careers in the IT industry, this is a rather complicated topic, and from all the educational materials that we have gone through while writing a course, it is rather difficult to understand what Internet Protocol IP is and what it eats with (or what does the letter “P” mean in an IP address? )







We will be glad if the video course " How the Internet works " will be useful for you.
