[techspeak] <span class="grammar">adj.</span> Describes an
application which requires a program to respond to stimuli within some
small upper limit of response time (typically milli- or microseconds).
Process control at a chemical plant is the <a href="../C/canonical.html"><i class="glossterm">canonical</i></a>
example. Such applications often require special operating systems
(because everything else must take a back seat to response time) and
speed-tuned hardware. </p></dd><dd><p> 2. <span class="grammar">adv.</span> In jargon, refers to
