WWW (World Wide Web) is part of the internet that contains linked text, image sound, and video documents. It is also define as an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet.

In 1989, London born Timothy Berners-Lee came up with the idea of the web as a way to share

files with others. The idea for the web came while Berners-Lee was working for the European Organization for Nuclear Research (CERN). Scientists by trade, Berners-Lee and others inside CERN were looking for ways to transmit information between each other electronically. To do so, they created a set of tools including a language (html), a browser and other utilities which allowed them to establish

communication.

The first web browser was invented in 1990 by Sir Tim Berners-Lee. His browser was called WorldWideWeb and later renamed Nexus. Many others were soon developed, with Marc Andreessen’s 1993 Mosaic (later called Netscape). Today, the major web browsers are Chrome, Safari, Internet Explorer, Opera, Netscape Navigator, Crazy Browser, Maxthron, UC Web Browser, Mozilla Firefox, Edge Etc.

The internet was first introduced into Nigeria in the year 1995. It was in reality a project work by RINAF (Regional Information Society Network for Africa). It was backed up financially by UNESCO. Several workshops were organised in order to educate the Nigerian populace. the first test running was conducted in Obafemi Awolowo University in 1995. By the late 1990’s the ”internet ” became a known term among the citizens of Nigeria.
