I am going to round off what I have learned in the social media training of RLabs Namibia. Before i go in into details, RLabs stands for reconstructing living labs and it was found by Marlon Paker, in 2008.  RLabs is a global movement and registered social enterprise that provides innovative solutions to address various complex.  Now what what I have learned, so far  is how to create different kind of accounts on the net, faster and easier than before.  Internet which is the connection of different computer connected to each other. WWW stand for world wide web and its a document saved on the server.
web 1.0 here people don't comment.  e.g newspaper
web 2.0 here the people do comment. e.g Facebook and twitter
web2.0 this is still to come.

Last but least on this, its protocol which is certain rules to follow, on how to do something.  Now in computer there is also a word called computer protocol which is the number on the computer to trace it or know its whereabouts.
