Cloud computing is like an automatic, always-where-you-go, synchronized backup. So if one of your computers fail, your data is still intact on another computer hooked up the the cloud.



Back then, what was most similar to cloud computing was copying books from 1 single book, and those books are updated about every 6 months or a year. (not seconds, but years! :D)
