Web 2.0 is a buzzword coined in 1999 to describe the emergence of technology and websites that extend beyond static pages to allow visitor interaction and user generated content, rather than information retrieval only. So-called Web 2.0 technologies brought about the social media revolution—allowing people to easily share interesting content with one another without using email.
Examples of Web 2.0 websites include:
Web Analytics is the field of Internet data and web site traffic analysis. A variety of Web analytics applications are available to collect, measure, analyze, and report website traffic. Analytics data is used to determine how various pages of a website perform, which allows site administrators to improve traffic and visitor engagement.See also: Google Analytics Top
Popular web browsers include Mozilla's Firefox, Google's Chrome, Microsoft's Internet Explorer, Opera, and Safari.Top
A web cache is a system for storing web pages on a device to reduce page load times on subsequent visits.
Web browsers implement caching in the form of reserved directories that temporarily store HTML files and images. These directories are sometimes called temporary Internet files.
Search engines also cache websites, to speed web page retrieval, lower bandwidth costs, and to reduce server load.Top
Web content consists of all text, images, applications, and various types of media published on the pages of a website.Top
("Search Bot" and "Web Spider" redirects here)

Web Standards are the formally recognized, continually evolving specifications that describe technical aspects of the Web. Although Web Standards encompass a broad range of technologies, they're most commonly associated with those responsible for the consistency and future-proofing of the languages used to develop accessible web pages.
Web standards help reduce the cost and complexity of web development, while increasing long-term website accessibility. See our external links on the business benefits of Web standards.See also: W3C, WHATWG, and HTML5 Top
The WHATWG (Web Hypertext Application Technology Working Group) is a growing community of web developers and professionals involved in maintaining HTML and related web standards technologies. The WHATWG was founded in 2004 by individuals from Apple, Mozilla and Opera with lead editor Ian Hickson, following the W3C's decision to abandon HTML to focus on XHTML.
The WHATWG published the first public draft of HTML5 in 2008, which was eventually led to the HTML5 Recommendation released by the W3C (World Wide Web Consortium) in 2014, as a final and complete specification.
The W3C and the WHATWG continue to work together on HTML specifications; however, the WHATWG maintains a continuously evolving, versionless "living standard" of HTML, while the W3C releases what the WHATWG refers to as "snapshots, such HTML 4.01 and the current HTML5 Recommendation.
The WHATWG spec is intended to describe what browsers should aim for, introducing new features and describing reality in as much, and as accurate, detail as possible. The W3C spec is intended to follow the W3C process to REC. - whatwg.org's FAQ
In addition to HTML, the WHATWG actively works on other web standard technologies, including Microdata and Web Forms 2.0See also: Web Standards and W3C Top
The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web, and publishes most of the recommendations that concern web developers. Since it's inception in 1994, the W3C has published more than 110 standards (also known as W3C Specifications), including specs for the basic coding languages of the web, such as HTML, the DOM, and CSS.
Founded by Tim Berners-Lee (inventor of the World Wide Web), the W3C's mission is:

WYSIWYG is an acronym for What You See Is What You Get. On the Web, WYSIWYG (pronounced WIZ-ee-wig) editors are sometimes used to publish web content by those who lack experience with markup languages. WYSIWYG editors allow users to arrange and format text, images, and other web content in "design view", with HTML and CSS created by the application.
WYSIWYG editors such as Dreamweaver, are convenient for beginners, but often produce redundant, non-Web standard, un-semantic HTML, that can result in slow-loading, inefficient, difficult to maintain websites.Top
