The concepts of RAID have been generalized to other storage devices, including
arrays of tapes, and even to the broadcast of data over wireless systems. When
applied to arrays of tapes, the RAID structures are able to recover data even if one
of the tapes in an array of tapes is damaged. When applied to broadcast of data,
a block of data is split into short units and is broadcast along with a parity unit;
if one of the units is not received for any reason, it can be reconstructed from the
other units.
