The Internet has had an impact on nearly every segment of society in modern nations. This is especially true in the world of information management and software. While programs used to be installed on your computer, be accessed by only you and did little sharing of information; the Internet has changed all of that. Today, 'collaboration' and 'knowledge sharing are the keys to success of software programs. And this is rapidly evolving into 'Web Services' - a version of software where optimized components all over the Internet work together to accomplish tasks for users.
