How does the internet work, and how do browsers fetch web pages?
This is a core CS (computer science) lecture that organizes network concepts following the OSI 7-layer flow so you can explain this question yourself.
It's structured with diagrams and flow-centered explanations to help you intuitively understand the structure,
and connects concepts like the transport layer (TCP/UDP), IP addresses, NAT, and HTTPS that frequently appear in technical interviews to actual questions.
