    The short version:

    Cloud computing refers to any hosted service, really. There are three main parts of cloud computing proper: internet-as-a-service, platform-as-a-service, and software-as-a-service.

    For most people, cloud computing means the act of running software and storing data in a physical location that is not where the user is, and is accessible through the internet. When you use iTunes, or save documents to Google Docs, or run Microsoft Outlook Web Access, all those things are examples of cloud computing.

    The "cloud" refers to any server where your data is stored so that you can access it from anywhere. This can apply to your personal files (documents, videos, etc.) or even software.

    For example, on that commercial for Windows, where the people are stuck waiting in an airport. They had some TV shows saved on their home computer, and because they saved them to the "cloud", they could access them from their laptop.

    Or, Google Docs. If you're unfamiliar, Google offers the ability to compose documents using only your internet browser. No software downloads whatsoever. Your data is saved on their servers, and you can also save it to your own computer of course. Since it's all online, it can be accessed from any computer. So if you're a student, maybe you started your homework in the school library, and then you can finished it at home without fiddling with a USB drive. Or if your job requires you to collaborate on something with people in other places, you can give everyone access to that document and everyone can access it form their own computers.

    Larry has a point. There is nothing particularly groundbreaking about remotely hosted data, but the word "cloud" really does have a nice marketing ring to it, doesn't it? What could make this idea groundbreaking is applying it to *big* things. Like, what if you could play video games without installing them? A company called OnLive tried that, but it doesn't work well due to technological limitations that prevent adequate streaming. Those limitations could be conquered in the future.

    Cloud Computing is a marketing term that means--taa-daa!--the Internet. Since the Internet nowadays is considered to be a slow, decrepit, and unsecure structure, marketing suits had to invent a new term to make it seem all shiny and new again. Thus was born Cloud Computing, a new way to spam, scam, and push more advertising into your face, and a new way to vacuum money from company's and people's wallets.

    In a nutshell, the Internet/Cloud Computing allows us to run apps from and to save data to remote servers. That's all. But it's still the Internet, and it's still full of hackers and spammers.

    not knowing where your computer is

    not having to know where your computer is - it's just "out there" somewhere, and may move around without telling you. As long as you can find it on DNS, it doesn't matter what hardware it's on or what country it's in.

    Except for data protection legislation. You can hope if you encrypt everything your data won't end up somewhere nasty and be read by your competitors somewhere where hacking is legal, like the US shipping suspects to Syria so they can be tortured.
