ABSTRACT
In the early 1990s the Internet- the system that links millions of computers around the world- became big news. By the late 1980s most professional computer users in the United States had access to the Internet, and the number of computers on the Internet began an explosive growth. Cloud computing is also at the heart of online social networking. Web-based social networking generally facilitates users' ability to create a profile on the web and interact with others. The World Wide Web was invented by Tim Berners-Lee. Its origins dated back to Berners-Lee's early interest in hypertext in 1980, long before the Internet was widely known. As usage of the Internet greatly broadened with the advent of the World Wide Web, many journalists, politicians, and others have presented it as a transformative technology of freedom and democracy. Smart-phones largely evolved from an earlier technology, Personal Digital Assistants (PDAs), which, like smartphones, were defined by their operating system or platform.
