it is Real-time computing is the study of hardware and software systems that must produce correct results within strict, bounded time constraints called deadlines. ## How it works / why it matters A real-time system is judged not only on the correctness of its output but on delivering that output before its deadline; missing a deadline is a failure (hard real-time) or a degradation (soft real-time). It underpins interactive and streaming signal-processing tasks such as live audio, video, and communications, where late data is effectively useless. ## Signs & universals Instantiates signal and tradeoff_balance. ## Related Related: [[Stream_processing]], Speech recognition, Data transmission, Wireless communication.  ## From the Real GENERATIVE library > Real-time computing (RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response.[1] Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".[2] ([Wikipedia](https://en.wikipedia.org/wiki/Real-time_computing))   *Built to the [[WT!P5_js_Microsim_Master_Class|p5.js Master Class]].*  ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Real-time_computing) : [Wikitube](https://en.wikitube.io/wiki/Real-time_computing) ## Previous hub tags Tree parents: [[Control_theory]] · [[Graph_theory]] · [[Information_theory]].
