• The Cloud delivers convenience by allowing you to: • Store documents, photos or videos online with services like or Microsoft SkyDrive

• “Imagine that a user has a computer file but not the program application needed to open or view the file. Cloud computing will allow the user to access the program over the Internet to view and edit the file as needed. Similarly, if a user needs a computer file he does not physically have with him, cloud computing allows him to access the file over the Internet, wherever the file happens to be stored.“
