What is a critical resource in the context of operating systems?
What is a critical resource in the context of operating systems?
- A resource that requires mutual exclusion among processes
- A resource that can be shared among multiple programs
- A resource that is unknown to the operating system
- A resource that can only be accessed by one program at a time (correct)
Why do processes have to express the requirement for mutual exclusion and not the operating system?
Why do processes have to express the requirement for mutual exclusion and not the operating system?
- The operating system lacks the capability to enforce mutual exclusion
- Operating systems cannot understand detailed process requirements (correct)
- The operating system delegates all control to processes
- Processes have better understanding of critical resources
What is a critical section in the context of a program?
What is a critical section in the context of a program?
- A section where processes communicate directly with the operating system
- A portion of code that modifies common variables (correct)
- A segment of code that accesses non-critical resources
- A section where multiple programs can simultaneously access resources
Why does the critical section problem arise in designing protocols for processes?
