Priority Based Scheduling
Priority Based Scheduling is a CPU scheduling algorithm used in operating systems where processes are assigned priority levels, and the scheduler selects the process with the highest priority to execute next. It can be preemptive or non-preemptive, with preemptive versions allowing higher-priority processes to interrupt lower-priority ones. This method is commonly applied in real-time systems, batch processing, and multi-tasking environments to manage resource allocation efficiently.
Developers should learn Priority Based Scheduling when working on operating systems, embedded systems, or real-time applications where task urgency varies, such as in robotics, avionics, or industrial control systems. It ensures critical processes receive immediate attention, improving system responsiveness and meeting deadlines, but requires careful priority assignment to avoid starvation of low-priority tasks.
