In the simplest terms, cloud computing means storing and accessing stuff over the Internet instead of on your computer's hard drive.

Think about it this way:  If you open a Word document on this computer and save it, where does it go?  It gets saved in a folder that can't leave this building.  If you wanted to open it at home you can't.  It's not mobile.  That means it doesn't travel with you.  However, if you were to save the same document 'in the cloud', you could access it at home or anywhere else for that matter.  As long as you have internet access, you can open anything that's saved 'in the clouds.' ....
