  A dropout is a small loss of data in an audio or video file on tape or disk.Continue Reading

• Ultra DMA (UDMA or Ultra DMA/33)

  Ultra DMA (UDMA, or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer's data paths (or bus) to the computer's random access memory (RAM).Continue Reading

• FRAM (ferroelectric RAM)

  FRAM (ferroelectric RAM) is random access memory that combines the fast read and write access of dynamic RAM (DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other ...Continue Reading
