The World Wide Web (“WWW” or simply the “Web“) is a global information medium which users can read and write via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet itself, but the Web is a service that operates over the Internet, just as e-mail also does. It is a system of interlinked hypertext documents accessed through the internet, by an application called a browser. It is a network service used in accessing, manipulating, and downloading a very large set of interlinked hypertext document and other files located on computers connected through the internet.
The World Wide Web can also be defined as a system of interconnection of several computers all over the world; forming a web-like networked structure. Technically it is the interconnection of internet servers that support specially formatted documents in HTML (Hypertext Markup Language)
Some notable application used to access the World Wide Web are; Firefox, Internet explorer, Google Chrome, Netscape navigator, etc.
Brief History of World Wide Web
The development of the web began in 1989 by British engineer and computer scientist Sir Tim Berners-Lee and his colleague at the centre for European Organisation for Nuclear Research in Geneva. Using concepts from his earlier hypertext systems like ENQUIRE, The team developed a protocol, Hypertext Transfer Protocol (HTTP), which standardized communication between the servers and clients. Their text-based web browser was released to the general public in 1992. The web gained rapid acceptance with the creation of a web browser called mosaic, developed in the USA by Marc Andreessen, Mosaic’s graphical user interface allowed the web to become, by far, the most popular Internet Protocol. Today, the World Wide Web has millions of active users. Presently, Sir Tim Berners-Lee is the Director of the World Wide Web Consortium (W3C).
