WebReal-time operating systems are designed to secretly follow the task within a given time. This is not simple and easy to complete the task within time. The real-time operating system utilizes all the hardware efficiently and completely. The main focus of the real-time operating system is not to save energy or resources. Even outside the realm of operating systems, real-time performance of processors can differ significantly. This becomes especially apparent when looking at microcontrollers and the number of cycles required for an interrupt to be processed.

A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is 'jitter'. A 'hard' real-time operating system (hard RTOS) has less jitter than a 'soft' real-time operating system (soft RTOS). A late answer is a wrong answer in a hard RTOS while a late answer is acceptable in a soft RTOS.
