DMA Is Short for Direct Memory Access, DMA is the transferring of data from one storage device to memory to another device without using the CPU.
Ultra-DMA is a standard developed by Quantum in conjunction with Intel that is twice as fast as the previous DMA interface. UDMA was first introduced in 1998 with the ATA-4 or ATA/ATAPI-4 standard and is capable of transferring data at 33.3 MBps, which is how the UDMA/33 or Ultra-DMA/33 names came about. Since its initial release and the approval of new ATA standards, the below UDMA standards are available.

Ultra DMA is an interface, commonly called IDE or EIDE. This is probably the interface your hard drive and CD-Rom use.

it helps hard drives to become faster and also takes off the load from the cpu so you can move large files with minimum cpu usage
