web 2.0 and the video I chose

The three video that we watched was about cloud computing, web 2.0 and the world wide web. What I learned in the video about "cloud computing" was that if you have a photo saved on a computer and the computer gets destroyed you picture will be gone. But if you put in on Facebook or something it'll go to a cloud thing so you can get the picture back even if your computer gets destroyed. The photo that you put on is in a factory with tons of other pictures that was in the "cloud" too. tons of computes hold all the photos that you ever put in the "cloud". The next video that we watched was "wed 2.0" it was about how digital text makes everything easier, and all the problems that can go wrong with it. The good things is that it makes your life easier because you can type all your stuff up fast. The bad things about it is copy right an stuff like that. The last video that I watched was called the "world wide wed" i guess this here thing is about some kind of cloud thing too and some girls business. I guess she uses the cloud to manage her stuff and yeah.
