Internet, the greatest educational tool of the 21st century.

I have read in a magazine that internet is the greatest educational tool of the 21-st century.  Having read it, I made a pause to think about it and this is what I conclude.  As a professional Italian language teacher and student of foreign languages, I find it so real. Not only have technology changed the way we see our world, it also have revolutionized each and every field of our life. Education-wise, the use and application of internet seems absolutely necessary.  For instance, one can have access to free dictionaries, e-books, or lookup a topic of interest on the web browser among others.  Nonetheless, internet has to be used wisely and cautiously.
