The idea
What is How the internet works?
How the internet works describes the global network of networks that lets any connected computer exchange data with any other. Data is broken into packets, each labelled with source and destination IP addresses, and routers pass them hop by hop until they are reassembled at the other end. The domain name system translates names like a website address into IP addresses, and layered protocols such as TCP, IP and HTTP make the whole thing reliable and understandable.

Where learners get stuck
Why How the internet works is hard
Learners picture the internet as a single central computer or the cloud, confuse the internet with the web, and cannot follow what happens between typing an address and a page appearing: DNS lookup, routing, TCP handshake, HTTP request.
The picture a good explanation starts with: A laptop sending a request through a home router, an ISP, several backbone routers and a DNS server to a web server, with packets drawn as small labelled envelopes.
A lesson, step by step
How a lesson on How the internet works goes
01
Ask
Type or say "What actually happens when I type a website address?" in your own words, in any of 26 languages.
02
Plan
The tutor plans a storyboard, one picture per idea, starting with a laptop sending a request through a home router, an ISP, several backbone routers and a DNS server to a web server, with packets drawn as small labelled envelopes.
03
Explain
It explains How the internet works out loud while the picture builds step by step, pitched to your level (Class 10-12 CBSE Computer Science and IP and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
05
Check
A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.
