Cloud computing means using software that is installed on the Internet. You can also save your work on another computer instead of the hard drive of your own PC or laptop. Music, letters, presentations and other projects can be stored on clouds, data storage areas on giant servers on the Internet.

There are many so-called web applications that can do the same as normal desktop software. Google Documents, for example, gives you a text editor, a slide show application and a program for creating tables and diagrams. You can use these programs for free – from any computer all over the world.

Up to now web browsers were only used to search for information on the Internet and show it. But now they have become something like operating systems which can give you almost everything that you have on your own PC desktop.
