What's the difference between "run" and "save" when I download a program?

Either of these options will lead you to the setup for the program and install it on your computer, but the difference lies in where the setup file opens from.

I'm sure you've all heard of the term "avatar" before, right? Besides being a 3D movie by James Cameron, it is also a pretty common term in today's Internet world. Still, you may have heard of it and still not know what it means or what all it entails.
