What is the difference between the job scheduler the CPU scheduler?

Answer 1

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.

Answer 2

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. :)
