Test your knowledge of the internet's history, how it works, and the wild story from ARPANET to AI.
99% of all intercontinental data travels through roughly 400 submarine cables on the ocean floor — not satellites. The internet's story is full of surprises like that, from a crashed first message ("LO" instead of "LOGIN") to a dancing baby becoming the first viral meme. How well do you really know the network that changed everything?
Each round presents 10 multiple-choice questions drawn from a pool of 50. Pick your answer, get instant feedback with a detailed explanation, and see your final score at the end. No signup or timer — just you and the fascinating history of the internet.
Questions cover the birth of ARPANET, the invention of the World Wide Web, how DNS and TCP/IP work, the rise of social media platforms, the dark web vs deep web, internet culture and memes, net neutrality, and the infrastructure — from undersea cables to data centers — that keeps the world connected.
No single person invented the internet. ARPANET, funded by the U.S. Department of Defense, launched in 1969. Vint Cerf and Bob Kahn developed TCP/IP in the 1970s. Tim Berners-Lee invented the World Wide Web in 1989 — but the web and the internet are not the same thing.
The internet is the global network of connected computers and infrastructure. The World Wide Web is a service that runs on top of the internet, using browsers and HTTP to access websites. Email, file transfer, and streaming also use the internet but are not the web.
The dark web is a tiny fraction of the internet, accessible only through special software like Tor. The deep web — content behind logins like email and banking — makes up over 90% of the internet. The surface web that search engines index is less than 10%.
