Is PCI slot the same as PCI1

[dugit]

I have taken the side of my desktop tower pc to see what type of slots I have (for firewire card) and I find that the slot (coloured blue)has printed by it PCI1 is this the same as PCI slot (I have 64 bit PC)

PCI1, meaning PCI slot number 1.

Many thanks for reply, seems obvious now at least it puts my mind to rest.
