[W/K] :: real time

  real time
       n 1: the actual time that it takes a process to occur;
            "information is updated in real time"
       2: (computer science) the time it takes for a process under
          computer control to occur

  real time 1. [techspeak] adj. 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 canonical example. Such applications often require
     special operating systems (because everything else must take a back seat
     to response time) and speed-tuned hardware. 2. adv. In jargon, refers to
     doing something while people are watching or waiting. "I asked her how
     to find the calling procedure's program counter on the stack and she
     came up with an algorithm in real time."
