Internet and Web

Tim Berners-Lee invented the World Wide Web in 1989, created HTML, and proposed the system of unique URLs. He developed these while working at CERN to facilitate information sharing among researchers.

YAHOO stands for 'Yet Another Hierarchy of Officious Oracle.' This playful name was chosen by founders Jerry Yang and David Filo as a reference to the fact that it was another directory of websites. Option A incorrectly uses 'Yes,' option B uses 'Official' instead of 'Officious,' and option D uses 'Your' instead of 'Yet.'

MIME stands for Multipurpose Internet Mail Extensions. It's a standard that extends the format of email to support text in character sets other than ASCII, multimedia content, and non-text attachments.

According to Tim O'Reilly, Web 2.0's core philosophy is democratization - empowering users to create, share, and collaborate rather than just consume content. This shift enabled platforms like blogs, wikis, and social networks where users actively participate rather than passively browse static pages.

Web 1.0 (1990s-early 2000s) was characterized by static, read-only websites where content was published by owners and consumed by users without interaction. These brochure-style sites featured HTML pages with minimal user engagement - no comments, no social sharing, no user-generated content.

An official online encyclopedia represents a Web 1.0 site because it's a static, read-only resource where experts publish content for users to consume without interaction. Unlike Web 2.0 sites with user comments, reviews, or contributions, Web 1.0 encyclopedias were one-way information sources without social features.

HTTP (Hypertext Transfer Protocol) is considered the backbone of the World Wide Web because it's the foundation protocol that enables communication between web servers and browsers. Every web page request, image load, and data transfer relies on HTTP to transport HTML, CSS, JavaScript, and other resources across the internet.

Email uses protocols like SMTP (Simple Mail Transfer Protocol), POP3, or IMAP to send and receive messages independently of HTTP. While web-based email services (Gmail, Outlook) use HTTP in their browser interfaces, the underlying email system operates through dedicated mail servers and protocols that don't require web browsers or HTTP.

Plug-ins are programs that enable web browsers to play multimedia files and perform additional tasks beyond basic HTML rendering. They extend browser functionality to handle audio, video, and interactive content.

WWW stands for World Wide Web, the global system of interconnected documents and resources accessed through the internet. It was invented by Tim Berners-Lee at CERN in 1989 and revolutionized information sharing.

PageRank is Google's core algorithm that ranks web pages based on link analysis, named after Larry Page. It revolutionized search by measuring page importance through the quantity and quality of links pointing to it.

Symbolics.com was the first registered domain name on March 15, 1985, by a computer systems company. Google and Hotmail were founded much later, while IBM registered their domain after Symbolics.

The first website was info.cern.ch, published by Tim Berners-Lee at CERN in 1991. Hotmail, Wikipedia, and IBM came years later - the web was invented at CERN, not by these companies.

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.
