At what point was the World Wide Web developed within a Swiss physics laboratory ?
Show answer Hide answer
Answer: C. 1990
Explanation
Tim Berners-Lee invented the World Wide Web while working at CERN in Geneva Switzerland. The foundational software protocols were successfully deployed and tested around 1990. This breakthrough revolutionized global information sharing by introducing hypertext links and web browsers. CERN is a premier European particle physics laboratory requiring advanced researcher communication tools. The invention combined hypertext concepts with the existing internet infrastructure created earlier. The source code was released to the public domain facilitating rapid global expansion.
Modern internet commerce and social media rely entirely on the foundational architecture built in 1990. Educational institutions rapidly adopted web technologies to distribute academic research worldwide. Historians mark this era as the beginning of the information age and digital communication. Option A points to 1980 which predates the actual invention of the World Wide Web protocols. Option B suggests 1985 when preliminary networking occurred before the web was officially developed. Option D selects 1995 which is years after the web had already been launched and commercialized.
