zero: vt. 1. To set to 0. Usually said of small pieces of data, such as bits
or words (esp. in the construction zero
out). 2. To erase; to discard all data from. Said of disks and
directories, where ‘zeroing’ need not involve actually writing
zeroes throughout the area being zeroed. One may speak of something being
logically zeroed rather than being
physically zeroed. See
scribble.
