Internet

onlinethe Internetweb
The World Wide Web, also known as the WWW and the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet.
The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

Sir Timothy John Berners-Lee (born 8 June 1955), also known as TimBL, is an English engineer and computer scientist, best known as the inventor of the World Wide Web.

Web page

Web pages are primarily text documents formatted and annotated with Hypertext Markup Language (HTML).
A web page (also written as webpage) is a document that is suitable for the World Wide Web and web browsers.

Web browser

browserweb browsersbrowsers
He wrote the first web browser in 1990 while employed at CERN near Geneva, Switzerland. With help from his colleague and fellow hypertext enthusiast Robert Cailliau he published a more formal proposal on 12 November 1990 to build a "Hypertext project" called "WorldWideWeb" (one word) as a "web" of "hypertext documents" to be viewed by "browsers" using a client–server architecture. A NeXT Computer was used by Berners-Lee as the world's first web server and also to write the first web browser, WorldWideWeb, in 1990.
A web browser (commonly referred to as a browser) is a software application for accessing information on the World Wide Web.

Hypertext

The World Wide Web, also known as the WWW and the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet.
Hypertext is one of the key underlying concepts of the World Wide Web, where Web pages are often written in the Hypertext Markup Language (HTML).

CERN is also the birthplace of the World Wide Web.

Website

web sitewebsitesonline
Multiple web pages with a common theme, a common domain name, or both, make up a website.
All publicly accessible websites collectively constitute the World Wide Web, while private websites, such as a company's website for its employees, are typically a part of an intranet.

Hyperlink

hyperlinkslinkslink
Embedded hyperlinks permit users to navigate between web pages.
The effect of following a hyperlink may vary with the hypertext system and may sometimes depend on the link itself; for instance, on the World Wide Web most hyperlinks cause the target document to replace the document being displayed, but some are marked to cause the target document to open in a new window.

Blog

blogsbloggerweblog
While the read-only goal was met, accessible authorship of web content took longer to mature, with the wiki concept, WebDAV, blogs, Web 2.0 and RSS/Atom.
A blog (a truncation of the expression "weblog") is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (posts).

Web 2.0

2.0enterprise 2.02.0 web
While the read-only goal was met, accessible authorship of web content took longer to mature, with the wiki concept, WebDAV, blogs, Web 2.0 and RSS/Atom.
Web 2.0, otherwise known as Participative (or Participatory) and Social Web, refers to World Wide Web websites that emphasize user-generated content, usability (ease of use, even by non-experts), participatory culture and interoperability (this means that a website can work well with other products, systems, and devices) for end users.

WebDAV

DAVDAV / HTTP(S)DAVx
While the read-only goal was met, accessible authorship of web content took longer to mature, with the wiki concept, WebDAV, blogs, Web 2.0 and RSS/Atom.
Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that allows clients to perform remote Web content authoring operations.

ENQUIRE

In March 1989 Berners-Lee issued a proposal to the management at CERN for a system called "Mesh" that referenced ENQUIRE, a database and software project he had built in 1980, which used the term "web" and described a more elaborate information management system based on links embedded in readable text: "Imagine, then, the references in this document all being associated with the network address of the thing to which they referred, so that while reading this document you could skip to them with a click of the mouse."
ENQUIRE was a software project written in 1980 by Tim Berners-Lee at CERN, which was the predecessor to the World Wide Web.

Client–server model

With help from his colleague and fellow hypertext enthusiast Robert Cailliau he published a more formal proposal on 12 November 1990 to build a "Hypertext project" called "WorldWideWeb" (one word) as a "web" of "hypertext documents" to be viewed by "browsers" using a client–server architecture.
Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.

Web server

A NeXT Computer was used by Berners-Lee as the world's first web server and also to write the first web browser, WorldWideWeb, in 1990.
Web server refers to server software, or hardware dedicated to running said software, that can serve contents to the World Wide Web.

WorldWideWeb

A NeXT Computer was used by Berners-Lee as the world's first web server and also to write the first web browser, WorldWideWeb, in 1990.
WorldWideWeb (later renamed to Nexus to avoid confusion between the software and the World Wide Web) was the first web browser and editor.

User-generated content

user-generateduser generated contentUGC
Website content can largely be provided by the publisher, or interactively where users contribute content or the content depends upon the users or their actions.
With the growth of the World Wide Web the focus moved to websites, several of which were based on user-generated content, including Wikipedia (2001) and Flickr (2004).

Global Internet usage

global InternetInternet usersdigital penetration
By 1985, the global Internet began to proliferate in Europe and the Domain Name System (upon which the Uniform Resource Locator is built) came into being.
It provides a multi-dimensional measure of the World Wide Web’s contribution to development and human rights globally.

Web navigation

Embedded hyperlinks permit users to navigate between web pages.
Once the world wide web was available, web navigation increasingly became a major aspect and role in jobs and everyday lives.

Usenet newsgroup

newsgroupnewsgroupsnews group
On 6 August 1991, Berners-Lee published a short summary of the World Wide Web project on the newsgroup alt.hypertext.
They are not devoted to publishing news, although they had been so intended when the internet was young.) Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web.

Gopher (protocol)

GopherGopher protocolgopher client
Coming two months after the announcement that the server implementation of the Gopher protocol was no longer free to use, this produced a rapid shift away from Gopher and towards the Web.
The Gopher protocol was strongly oriented towards a menu-document design and presented an alternative to the World Wide Web in its early stages, but ultimately Hypertext Transfer Protocol (HTTP) became the dominant protocol.

HyperCard

cardsHypercard stacks
Unlike predecessors such as HyperCard, the World Wide Web was non-proprietary, making it possible to develop servers and clients independently and to add extensions without licensing restrictions.
It was among the first successful hypermedia systems before the World Wide Web.

Memex

DARPA's Memexhypertext system
Both Nelson and Engelbart were in turn inspired by Vannevar Bush's microfilm-based memex, which was described in the 1945 essay "As We May Think".
The concept of the memex influenced the development of early hypertext systems (eventually leading to the creation of the World Wide Web) and personal knowledge base software.

ViolaWWW

An early popular web browser was ViolaWWW for Unix and the X Windowing System.
ViolaWWW is a discontinued browser, the first to be popular for the World Wide Web (WWW).

Berners-Lee created the system, calling it World Wide Web, between September and December 1990.

Semantic Web

Berners-Lee continued to stay involved in guiding the development of web standards, such as the markup languages to compose web pages and he advocated his vision of a Semantic Web.
The Semantic Web is an extension of the World Wide Web through standards by the World Wide Web Consortium (W3C).
