Non-Preemptive scheduling: Running process is executed till its completion. When a process switches from the running state to ready state (when interrupt occurs). When a process switches from the waiting state to the ready state (completion of I/O).Ģ. There is an overhead of context switching.

Ready queue can be implemented as priority queue, unordered list, FIFO queue etc.Īll the processes that are in ready queue and are ready to execute but waiting for a chance to run on the CPU.ĭispatcher: It is a module that give control of the CPU to process selected by CPU scheduler (short term scheduler).ĭifference between dispatcher and scheduler : Preemptive scheduling: Running process is interrupted for some amount of time and resumed later when the priority task has finished its execution. <<"\t"< This is where the problem starts, this is anycodings_c++ where the average waiting time code starts, anycodings_c++ why does it always It will sort the processes according to their arrival time*/ *sort is a predefined funcion defined in algorithm.h header file, My average anycodings_c++ waiting time is getting shown in infinity. This is a program in C++ about the CPU anycodings_c++ Scheduling Algorithm - SJF (Non Preemptive) anycodings_c++ I tried to find out the average waiting time anycodings_c++ but I am always getting an error.
