Q. RTOS(Real-time Operating System) vs GPOS(General Purpose Operating System)

|RTOS|GPOS| |------------|------------| |RTOS has unfair scheduling i.e. scheduling is based on priority|GPOS has fair scheduling i.e. it can be adjusted dynamically for optimized throughout| |Kernel is pre-emptive either completely or up to maximum degree|Kernel is non-preemptive or has long non-preemptive sections| |Priority inversion is a major issue|Priority inversion usually remains unnoticed| |It has a predictable behaviour|There is no predictability| |It works under wrost case assumptions|It optimizes for the average case|
|It does not have a large memory|It has a large memory|
