Introduction With CPU’s become faster and more capable of handling many programs/processes at any single time‚ a program is essential where the different processes of programs are manages and all given time to be processed by the CPU. The CPU has its limitations and cannot process anything at once. Enter the process Scheduler. The Scheduler helps the CPU by assigning the next process to be processed by the CPU Body In all the operating systems‚ schedulers are a critical component of the
