Introduction !cont(# Off$line processin"

The entire input si"nal resides in the computer as the

same time( *ll of the information is simultaneousl& availa'le to the

processin" pro"ram(

tomo"raph& and M/I( PC and mainframes.

Introduction !cont(# On$line processin"

The output si"nal is produced at the same time that the

input si"nal is 'ein" acuired( +("( telephone. radar.hearin" aids(
