Non-Preemptive: Non-preemptive algorithms are designed so that once a process enters the running state(is allowed a process), it is not removed from the processor until it has completed its service time (or it explicitly yields the processor).
context_switch() is called only when the process terminates or blocks.
Preemptive: Preemptive algorithms are driven by the notion of prioritized computation. The process with the highest priority should always be the one currently using the processor. If a process is currently using the processor and a new process with a higher priority enters, the ready list, the process on the processor should be removed and returned to the ready list until it is once again the highest-priority process in the system.
context_switch() is called even when the process is running usually done via a timer interrupt.

What is the difference between primitive and non primitive CPU scheduling algorithm?
In Non-Primitive CPU Algo. once a process is given to the CPU it cannot be preempt,but in primitive Algo. it can be.
Examples of primitive and non primitive scheduling?
The latter isn't primitive. Most likely it means 'non trivial', 'adaptive' or 'sophisticated'.

What is the comparative form of the word primitive?

How do you spell primitive?
Primitive is spelled the way you spelled it: primitive.
What type of scheduling is there in RTOS?
A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.
Is round robin scheduling preemptive or non primitive?
If a process does not complete before its CPU-time expires, the CPU is preempted and given to the next process waiting in a queue. The preempted process is then placed at the back of the ready list. Round Robin Scheduling is preemptive (at the end of time-slice) therefore it is effective in time-sharing environments in which the system needs to guarantee reasonable response times for interactive users.
What is the meaning of sequential scheduling?
It means scheduling one after another.
What is stream scheduling?
Stream Scheduling is a scheduling system where there is a steady stream/flow of patients at set appointments throughout the day.
