Video Cards and PCI Slots

[hardware noob]

Really easy question that probably has a very obvious answer. How can something like this fit into a PCI slot like this ? They're both PCI, so it seems they should fit, but doesn't the fact that the card has 3 prong-things and that the slot only has 2 mean something?

Thanks.

The front part with two prong things will fit into the large slot, and the shorter thing fits into the smaller slot.

It all works out in the end.
