This question was posed to me in exam.

The query is from Process Scheduling Queues in chapter Processes of Operating System

Answer 1

Correct option is (c) The frequency of their execution

To explain I would say: The primary distinction between the short-term scheduler and the long-term scheduler is the frequency of their execution. The short-term scheduler executes frequently while the long-term scheduler executes much less frequently.
