CPU Scheduling<\/a> is the process of determining which process will have exclusive use of the CPU while another is paused. The basic goal of CPU scheduling is to ensure that whenever the CPU is idle, the OS chooses at least one of the programs in the ready queue to run. The CPU scheduler will be in charge of the selecting process. It chooses from among the processes in memory that are ready to run.<\/p>\n\n\n\n

Types <\/strong><\/h2>\n\n\n\n

1. Preemptive scheduling<\/strong><\/p>\n\n\n\n

Tasks are generally assigned with their priorities in Preemptive Scheduling. Even if the lower priority activity is still running, it is sometimes necessary to run a higher priority task before a lower priority task.<\/p>\n\n\n\n

2. Non-preemptive scheduling<\/strong><\/p>\n\n\n\n

The CPU has been assigned to a certain process in this scheduling mechanism. The process that keeps the CPU occupied will either switch context or terminate to relieve the CPU. It’s the only method that works across a variety of hardware platforms. That’s because, unlike preemptive scheduling, it doesn’t require any particular hardware (such as a timer).<\/p>\n\n\n\n
