Multi-level queue 196 scheduling algorithm is used in scenarios where the processes can be classified into groups based on property like process type, CPU time, IO access, memory size, etc. One general classification of the processes is foreground processes and background processes. In a multi-level queue scheduling algorithm, there will be n number of queues, where n is the number of groups the processes are classified into. Each queue will be assigned a priority and will have its own scheduling algorithm like Round-robin scheduling 194 or FCFS. -Multi-level queue 196 scheduling algorithm is used in scenarios where the processes can be classified into groups based on property like process type, CPU time, IO access, memory size, etc. One general classification of the processes is foreground processes and background processes.
