Tim Berners-Lee is the inventor of WWW(World Wide Web). The invention of WWW started in the year 1989 when Tim came up with a new concept. It all happened during the particle physics research when Tim came up with the idea of enabling all the research people from remote sites to organize and pool together the research information around the globe.
And with this idea, Tim thought of making all these documents as files which can be easily downloaded to user's computers. ( Basically by this method,we could link the text in the file itself).
In simple words, documentation of all these information would thus represent as a WEB of information held in electronic form on all computers across the world.
He was the one who first implemented the successful communication between a HTTP(Hyper Text Transfer Protocol) client and a server via the internet.
