What is Cloud Computing?

I think Cloud Computing is doing something on your computer or mobile device when the application is NOT on your computer but on a remote server somewhere. Google is trying to create (maybe they already have) an operating system that is on the cloud. You won't have to download anything, update anything you just connect to the internet. One man in the video called it the "big computer" that we all connect to. For example if PowerPoint was on the Cloud, I wouldn't have to worry about making a presentation and not being able to show it on a different computer because they had an older version of it installed. I could use Google Docs Presentation tool and I'd be able to pull it up on any computer that had an internet connection. Web 2.0 tools are more the applications we use that we can be interactive with. I think of Wikipedia, Facebook, blogs, YouTube when I think of Web 2.0. We might have to have a program on our computer to access these but they can be edited and viewed by anyone with an internet connection. I liked this You Tube of Web 2.0. It really gives you some things to think about.
