In the simplest terms, cloud computing means storing , accessing data and programs over the Internet instead of your computer's hard drive.Having your data stored offsite in the cloud makes it accessible from anywhere without the hassle of maintaining your own local storage and file-serving systems. It makes all the difference in a disaster, too.The ability to back up files, store them in the cloud, and automatically sync all that data across multiple devices has radically changed the way we use computers, mobile phones, and other Internet-connected devices. That data could comprise home movies, your personal music collections, or work files that you and a colleague are collaboratively editing together. No matter what you put into a cloud storage and syncing solution, the benefit of being able to access it nearly anywhere is phenomenal.
