In a system where the number of processes exceeds the number of available resources, what is an effective strategy to prevent deadlocks?
In a system where the number of processes exceeds the number of available resources, what is an effective strategy to prevent deadlocks?
- Give resources to the process that has been waiting for the shortest amount of time, since this is most efficient.
- Allocate resources to processes on a rotating basis, regardless of their immediate needs.
- Grant every resource request immediately to maximize resource utilization.
- Require each process to request all required resources at once, before execution. (correct)
What is the primary impact of increasing the degree of multiprogramming in an operating system?
What is the primary impact of increasing the degree of multiprogramming in an operating system?
- It simplifies the scheduling algorithms needed for efficient resource allocation.
- It improves CPU utilization by overlapping CPU bursts and I/O bursts. (correct)
- It reduces the number of processes in the ready queue.
- It decreases CPU utilization due to increased context switching overhead.
