The Internet is defined as the worldwide interconnection of individual networks operated by government, industry, academia, and private parties. Originally the Internet served to interconnect laboratories engaged in government research, and since 1994 it has been expanded to serve millions of users and a multitude of purposes in all parts of the world.
Internet is changing all the time. Two things, in our opinion, have marked it’s evolution recently: the social web and mobile technology. These two innovations have changed the way people use the Internet. In the social web people have found a new way to communicate. Since its creation in 2004, Facebook has grown into a worldwide network of nearly 1,000 million subscribers. Mobile technology, on the other hand, has made possible a much greater reach of the Internet, increasing the number of Internet users everywhere.
