Concurrency Control
The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for …
Question
**Question:** Describe the Medium-Term Scheduler in detail. The medium-term scheduler is a part of the operating system responsible for managing which processes are kept in memory and which are swapped out to disk. It typically operates in situations where the system is facing memory constraints and needs to optimize the execution of processes. The medium-term scheduler dynamically adjusts the level of multiprogramming by swapping processes in and out of the memory, improving system performance and ensuring that high-priority tasks have access to necessary resources. By controlling the mix of processes in memory, it helps to balance the load and manage resource allocation effectively.
