Internet and Web

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.

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.

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.

A valid email address must contain the '@' symbol and a domain name with extension. Option C '[email protected]' follows this correct format with username, @ symbol, and domain with .com extension. Option A lacks '@', B is a website URL, and D is missing the domain extension.

A web browser is a software application that enables users to access and navigate websites on the World Wide Web. Common examples include Chrome, Firefox, and Safari. It is not an actual spider, a storage computer, or a person - it is software installed on your device.
