Is the Process Scheduler is also called the high-level scheduler?
No. The Job Scheduler is the high-level scheduler.
What is the difference between process scheduling and CPU scheduling?
1. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler.2. Job scheduler selects the processes from the job pool and load them in to the memory for execution. in other hand CPU scheduler selects among the processes that are in ready to execute and allocate the CPU to one of them.3. CPU scheduler is faster than the process scheduler.Read more: What_is_the_difference_between_the_job_scheduler_the_CPU_scheduler
What is the difference between the job scheduler the CPU scheduler?

CPU scheduler is faster than the process scheduler.
How does the Linux process scheduler prioritize processes?
The scheduler itself actually doesn't assign priority on its own, typically. Usually a process will try to specify its own priority, but priorities can be changed through system calls, usually made by process managers. Of course, the scheduler can refuse to allow a process a specified priority if it feels the process doesn't have the actual demand to justify it. Remember, anything in userspace pretty much has to ask permission to do just about anything from the kernel.
What is control-m?
Control-M is work load scheduler to automate daily business process.
What is the differences between the job scheduling and process scheduling?
Jobs or processes are the same. Whereas, Job scheduler and CPU scheduler are two different terms. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. While Job scheduler selects the processes from the job pool (Job pool is on the Hard disk) and load them in to the memory (Main Memory or RAM) for execution. in other hand CPU scheduler selects among the processes (in RAM) that are ready for execution and allocates the CPU to one of them. Hope I got it right and answered your query. Sorry for any mistakes as I'm not perfect as well. :) Cheers, KV
What are the different functions of Syntax phase Scheduler?
Syntax Phase Scheduler basically check which process should be allocate from the ready queue to the CPU for execution.
What is a preemptive and non preemptive algorithm and explain with example?
Preemptive scheduler reruns scheduling decision when process becomes ready. If the new process has priority over running process, the CPU preempts the running process and executes the new process. Non-preemptive scheduler only does scheduling decision when running process voluntarily gives up CPU. In effect, it allows every running process to finish its CPU burst.
What is difference between a scheduler and a dispatcher?
DISPATCHER?The dispatcher is the module that gives control of the CPU to the process selected by the short-time scheduler(selects from among the processes that are ready to execute).The function involves :Swithching contextSwitching to user modeJumping to the proper location in the user program to restart that program.SCHEDULER? Normally there are 3 types of schedulers are available in operating systems.1. Long term scheduler2. Mid term scheduler3. Short term schedulerThe short term scheduler is also called as the dispatcher which selects the process from the waiting queue and allocates the CPU to that process.Whereas the Long term scheduler (Admission scheduler) decides which process should be placed in the main memory and updates the waiting queue. This long scheduler is important in the large bound systems like super computers and may not be used frequently as the short term scheduler.The mis term scheduler available in all systems which is responsible for the swapping in and out operations which means loading the process into, main memory from secondary memory (swap in) and take out the process from main memory and store it into the secondary memory (swap out).
What is job scheduler and dispatcher?

What is the main difference between a preemptive scheduler and a non-preemptive scheduler?
Non-preemptive scheduler gives a process control of computer until it gives it up. Preemptive scheduler ensures that all processes are given equal(or different) priority, so they run only for a short amount of time, before control is given to another process. Which means that preemptive system is capable of running many processes 'at once', without crashing when one process refuses to give up CPU control If a bug like infinite loop, or a process refusing to give up control(a virus for example) is encountered, only thing left to do is to reset the system.
Which scheduler controls the degree of multiprogramming?
Long Term Scheduler
