A system of Internet servers that support specially formatted documents. The documents are formatted in amarkup language called HTML (HyperText MarkupLanguage) that supports links to other documents, aswell as graphics, audio, and video files. This means youcan jump from one document to another simplyby clicking on hot spots. Not all Internet servers arepart of the World Wide Web.There are several applications called Webbrowsers that make it easy to access the World WideWeb; Two of the most popular being Firefox andMicrosofts Internet Explorer.The World Wide Web (or the proper World-Wide Web;abbreviated as WWW or W3, and commonly known as theWeb) is a system of interlinked hypertext documentsaccessed via the Internet. With a web browser, one canview web pages that may contain text, images, videos, andother multimedia and navigate between them via hyperlinks.
1958The U.S. Department of Defenselaunched the Advanced ResearchProjects Agency (ARPA) whichdeveloped a rudimentary Internet in the1960s - what the WWW rides on. Itsinteresting to note that ARPA cameabout due to perceived threats relatingto the Cold War. This Department ofDefense project would evolve intoARPANET in the years to come and bemade accessible to all.
1960sLeonard Kleinrock at MIT publishesthe first paper on packet switchingtheory in July 1961. DouglasEngelbart developed NLS - an onlinehyperlinking system - and alsoinvented the mouse; an essential toolthat wouldnt gain popularity untilnearly 20 years later. Ted Nelsoncoins the term "hypertext".
1970sRay Tomlinson developed the firstelectronic mail system. Bob Kahn andVint Cerf develop the TCP/IPnetworking protocols which are stillthe workhorses of the Internettoday. Ethernet was also developedduring this decade. The first spam message was sent bya DEC marketing representative to aslew of ARPANET addresses in 1978.
1980sThe Domain Name System (DNS) wasintroduced in 1984. DNS translatesdomain names into IP addresses and viceversa. It was also in 1984 that Applelaunched the first personal computer.Fidonet, the first dialup network toconnect personal computers, wasestablished in 1983.Tim Berners-Lee published a paper callInformation Management: AProposal, that detailed how the WorldWide Web would operate in 1989. Hecreates a hyperlinked database systemfor use in connecting databases across aclosed network.
1990Berners-Lee coined the WorldWide Web term. It was actuallythe name of the browser hecreated. The first Web serverand Web page at nxoc01.cern.chwas also trialed late that year;but it was only accessible viainvitation. nxoc01.cern.ch waslater renamedto info.cern.ch, which is stillactive today.
1991Berners-Lee web server and browser wasmade publicly accessible after makingthis announcement and other serversbegan appearing around the world. 1992By the end of 1992, there wereabout 26 publicly accessible sitesavailable on the World Wide web.Surfing the Internet" is coined byJean Armour Polly.
1993Marc Andreessen and Eric Bina releasethe first version of the Mosaicbrowser. This is the first browser tosupport the display of images.The first image based banner ad is alsosold during this year by Global NetNavigator (GNN) which was the firstcommercially supported webpublication. HotWired soon follows byselling a banner ad placement on theirsite.
1994The worlds first search engines, Web Crawlerand Lycos, are launched. Jerry Yang and DavidFilo publish "Jerrys Guide to the World WideWeb" online, which will evolve into Yahoo. Thefirst version of Netscape Navigator is alsoreleased.The first secure ecommerce transaction isreported to have occurred Aug. 11, 1994. Theproduct was the CD "Ten Summoners Tales"by Sting. The Fraunhofer Society release thefirst software MP3 encoder called l3enc.The first banner ad appears on HotWired.com
Tim Berners-LeeSir Timothy John "Tim" Berners-Lee, (born 8 June 1955), alsoknown as "TimBL", is a British computer scientist, MIT professorand the inventor of the World Wide Web. He made a proposalfor an information management system in March 1989 and on25 December 1990, with the help of Robert Cailliau and a youngstudent at CERN, he implemented the first successfulcommunication between a Hypertext Transfer Protocol (HTTP)client and server via the Internet.In the process of developing, he developed three essentialtechnologies:a system of globally unique identifiers for resources on the Web andelsewhere, the Universal Document Identifier (UDI), later knownas Uniform Resource Locator (URL) and Uniform ResourceIdentifier (URI);the publishing language HyperText Markup Language (HTML);the Hypertext Transfer Protocol (HTTP)
Robert Cailliau-> most well-known for theproposal, developed with TimBerners-Lee, ofa hypertext system foraccessingdocumentation, whicheventually led to the creation ofthe World Wide Web.
