The actual time during which a process or event occurs: "information updated in real time". This topic covers how to control the Raspberry Pi in real time, how to use software in real time, and any other use of the Raspberry Pi in which real time control is needed. Not to be confused with real-time clock.
Real-time computing describes computer systems (hardware and software) subject to a real-time constraint. It must guarantee a reaction within specified time constraints between event (e.g. an interrupt) to system response.
