zoo /day 't */ (Or "raw data ")
Numbers , {characters }, {images }, or other method of recording ,
in a form which can be assessed by a human or (especially )
input into a {computer }, stored and {processed } there , or
transmitted on some {digital channel }. Computers nearly
always represent data in {binary }.
Data on its own has no meaning , only when interpreted by some
kind of {data processing system } does it take on meaning and
become {information }.
For example , the binary data 01110101 might represent the
integer 117 or the {ASCII } lower case U character or the blue
component of a pixel in some {video }. Which of these it
represents is determined by the way it is processed (added ,
printed , displayed , etc .). Even these numbers , characters or
pixels however are still not really information until their
context is known , e .g . my bank balance is £117 , there are two
Us in "vacuum ", you have blue eyes .
