Understanding Real- Time Operating Systems

A Real- Time Operating System (RTOS) is a computing environmentat that reacts to input with a specific time period. A real- time deadline can be small that system reaction appears instantaineous. Thee definiing characteristic of an RTOS is its ability to activite that critical tasks complete with in specified time displitints.
