ARPANET (Advanced Research Projects Agency Network) was the precursor to the modern internet, developed by the US Department of Defense. It established the foundational networking protocols that evolved into today's global internet.

Tim Berners-Lee invented the World Wide Web (WWW) in 1989 at CERN. He developed the first web browser, web server, and the fundamental protocols (HTTP, HTML) that power the internet today. Steve Jobs founded Apple, Narayan Murthy co-founded Infosys, and Marc Andersen co-founded Netscape - none invented the WWW.

URL stands for Uniform Resource Locator, which is the address of a specific resource on the internet. It specifies the location of a resource on a computer network and the mechanism for retrieving it. The other options are fictional expansions that don't match the standard definition.

ICANN (Internet Corporation for Assigned Names and Numbers) is the global non-profit organization responsible for coordinating internet domain names and IP addresses. CIA and RAW are intelligence agencies, and 'ISI' is not the correct organization name for this function.

In HTTPS, the 's' stands for 'secure' - it indicates the connection is encrypted using SSL/TLS protocols. While 'secured' or 'security' might seem logical, the standard abbreviation is simply 'secure'. 'Simple' is incorrect as HTTPS provides more security than HTTP.

Larry Page and Sergey Brin founded Google in 1998 while they were Ph.D. students at Stanford University. They developed the PageRank algorithm that became the foundation of Google's search engine. Microsoft, Yahoo, and Amazon were founded by different people.

Jack Smith co-founded Hotmail along with Sabeer Bhatia in 1996. Hotmail was one of the first web-based email services and was later acquired by Microsoft. Bill Gates (Microsoft), Steve Jobs (Apple), and Ajay Bhat are not associated with Hotmail's founding.

YAHOO stands for 'Yet Another Hierarchical Officious Oracle' - a backronym coined by founders David Filo and Jerry Yang. The name originally started as 'Jerry and David's Guide to the World Wide Web' before being changed to the acronym YAHOO. It is indeed an acronym, not a surname.

ISP stands for Internet Service Provider - companies that provide individuals and organizations with access to the internet. ISPs offer services like broadband, dial-up, and fiber connections. 'Security Protocol', 'Survey Period', and 'Integrated Service Provider' are incorrect expansions.

Rust forms when iron reacts with oxygen in the presence of moisture/water, creating iron oxide. Only iron and iron-containing metals (like steel) rust. Gold and silver are noble metals that don't oxidize under normal conditions.
