How do I extend the desktop when using dual monitors?

What I would like to do is to Connect Two Monitors to my Computer (which I have already done)

But how do I display different Content on each Monitor.

As an example, I would like one Monitor to display my email all the time while using the other Monitor for normal Surfing

Is this possible?

If so how do I do it?

I have no idea how to do this so non Tech instructions would be appreciated.
