For Ultra Ata we have a term and definition in Technology.

(a.k.a. ATA-4, Ultra DMA, ATA-33, DMA-33) Ultra ATA is the latest specification for the ATA/EIDE disk controller standard. What do all these acronyms mean? EIDE, or "Enhance Integrated Electronics Interface" is a technology that puts all of the controller electronics for disk drives onto the drives themselves. (The controllery goodness is backed right in!) Ultra ATA allows for much faster data transfers that are twice as fast as the previous ATA-2 (up to 33.3 megabits per second). More acronym fun: "ATA" stands for "Advanced Technology Attachment" and is synonymous with IDE. "DMA" stands for "Direct Memory Access" and refers to the controller's ability to talk directly between memory and the disk drive without bothering the computer's CPU. See also EIDE.
