the webinar “How Does the Internet work?” covered a lot of interesting topics in a clear and simple way. It started with an introduction, then explained what switches and routers do and why they’re important.
the sessions on “What does the internet represent?” (Parts 1–3) really helped me understand how everything connects together. I also learned how computers connect to the internet, how Wide Area Networks (WAN) function, and what Internet Service Providers (ISPs) actually do.
each part built on the last, making it easy to follow. overall, it was a great and informative overview of how the internet works. thank you
