I completed the basics and applied courses, and it was a very interesting lecture because it explained with examples that I could see around me (routers, ISPs). As someone who thinks that lectures that make you interested are the best learning, this was the best lecture. I will visit again next time. Thank you!

Wow~~! You've all completed it. It's not easy to complete a lecture, so thank you for your hard work. I'm also so happy to receive such good evaluations and feedback. :)

This lecture guides those who have learned the basic course of network core theory by memorizing it to understand theories in more depth. It covers more in-depth theories such as NAT technology, the operating principle of Internet routers, load distribution system principles, and VPN technology principles. The goal of this lecture is also to finish it by memorizing it! You can do it!
