One of the differences between the long-term scheduler and the short-term scheduler is:Question 8Select one:The limit on the number of processes they can handleHow frequently each are invoked.The type of processes they schedule

The main differences between the long-term scheduler and the short-term scheduler are:

1. Frequency of Invocation: The long-term scheduler, also known as the admission scheduler, is invoked less frequently compared to the short-term scheduler. This is because the long-term scheduler has to make a more complex decision of which processes should be moved from the secondary memory (hard disk) to the main memory (RAM). On the other hand, the short-term scheduler, also known as the CPU scheduler, is invoked very frequently (in the order of milliseconds) to manage the execution of processes in the CPU.

2. Type of Processes They Schedule: The long-term scheduler controls the admission of new processes into the system, deciding which processes should be brought into the ready queue. The short-term scheduler, on the other hand, schedules the execution of these processes in the CPU.

3. Limit on the Number of Processes: The long-term scheduler controls the degree of multiprogramming, i.e., the number of processes in memory. If the long-term scheduler frequently admits new processes, then the degree of multiprogramming increases. The short-term scheduler, however, does not have control over the number of processes. It only determines which process in the ready queue will be executed next by the CPU.

So, the correct answer is: All of the above.
