UDMA and UATA

[databyss]

I just got this mobo as the foundation for my new rig: http://www.ecs.com.tw/products/k7s5a.htm

and now I'm looking to get a hard drive for it. the boards description says this:
"Dual PCI IDE interfaces - support four IDE devices (PIO mode 4, DMA Mode 2, Ultra DMA 33/66/100)"

My question is what's the difference between Ultra DMA and Ultra ATA and are they compatible?

Could I install a Ultra ATA 100 hard drive on this?

I'm just starting to learn all about the hardware aspect of things so any help would be appreciated....
