to operate normally.
Striping: see RAID
UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also called
UltraATA. Without proper UltraDMA controller, your system cannot take advantage of higher
data transfer rates of the new UltraDMA/UltraATA hard drives.
USB (Universal Serial Bus): a versatile port. This one port type can function as a serial,
parallel, mouse, keyboard or joystick port. It is fast enough to support video transfer, and is
capable of supporting up to 127 daisy-chained peripheral devices.
