Express Cards? What do they do?

Hi all
Since this is a 'newbie' forum, I hope my question isn't too elementary for most of the readers. This forum is called 'computer newbies', but some of the questions I see here are pretty 'high-tech' to me.
I have a new laptop with an Express Card slot on it. What info/programs do Express Cards usually contain? Any examples? Nothing in my manual that explains what Express Cards do.
As you can tell, I'm sort of a 'low-tech' guy so keep any replies to my low level of expertise.

Generally, Video Cards Are Indicated PCI-Express

In reply to: Express Cards? What do they do?

The PCI slot is designed for a specific type of slide-in card.. Likewise for the AGP slot which is/was generally used for video cards.. The PCI-E (Express) slot maintains software compatibility with traditional PCI, but replaces the slower physical bus of PCI with a high-speed (2.5 Gb/s) serial bus. In many of the newer computers, it's now replaced the older AGP slot for graphics cards.

Hope this helps.
