temporary power to the computer when the Local Commercial
power is interrupted, allows time to save the data files, close
applications that are open, and turn AC power OFF normally,
without losing data.
USB: Universal Serial Bus. A new external bus standard that
supports data transfer rates of 12Mbps (12 million bits per
second). A single USB port can be used to connect up to 127
peripheral devices, such as mice, modems and keyboards. USB

hardware standard and the lowest common denominator for all

processor does not have to “wait” for memory, and can access
data as fast as needed.
