The Cloud is an interesting term that seems to be floating around at the moment.
The idea is that a large majority of the processing that your computer does can be done online. This could free up your computer’s processor to work more economically. A great idea in principal; but it’s very important that private information is kept secure.
I would advise anyone storing data online, to ensure it’s contained in a secure environment. After all, you wouldn’t give your personal information to everyone.
