    hi , thanks for all your help , I managed to get 95% for my operating systems module at university last semester & it's all because of your teaching 🙏

    System processes are used to run system programs. Ex- Interrupt.
    High priority system process.
    Interactive process - When u r interacting with the application..
    Like working on MS office.
    Interacting continuously through
    console or command, etc.
    Batch process - Runs in the background.
    Multilevel queue -
    Different types of processes are placed in df. types of ready queue.
    Each queue is having its own scheduling algorithm.
    "Which queue will follow which scheduling algorithm?"
    This depends on who is going to implement the scenario i.e, implementer.
    ( Example - For system process: Round Robin scheduling algorithm)
    No. Of queues also depends on the implementer.
    Imp: In a Multilevel queue, if a process is running then from its execution to termination the process cannot change its queue i e it cannot migrate from one queue to another queue.
    It's permanently assigned to the queue in which the process has arrived.
    2nd imp-
    No interactive process can be executed unless & until "SYSTEM PROCESS QUEUE" gets empty.
    Same goes with the batch + interactive process.
    Bcoz of such cause, it leads to starvation. (Disadvantage)
    We can do "aging".
    i.e upgrading - To place the process into the next ready queue to get its execution faster. (Migration of process from one queue to another) - known as Multilevel Feedback Queue Scheduling Algorithm.
    Look, not only low priority process are promoted to the queues of higher priority but also "higher priority process are demoted from higher priority queue to lower priority queue."
    Go watch how : -2:55
    Implementation of MFQ scheduling is tough, it all depends on the implementer.
    How many queues?, which queue is using which scheduling algorithm, when to promote a process ( after how many time quantum) , when to demote a process, etc.
    Thank you!❤
