What risk arises when processes P0 and P1 do not have a mechanism to prevent them from accessing the kernel variable next_available_pid simultaneously?
What risk arises when processes P0 and P1 do not have a mechanism to prevent them from accessing the kernel variable next_available_pid simultaneously?
- Two different processes may end up sharing the same process identifier (pid). (correct)
- The processes may lose access to their critical sections.
- The processes may enter an infinite loop in the critical section.
- The processes may deadlock due to a shared resource conflict.
What is the main objective of a protocol designed to address the critical section problem in operating systems?
What is the main objective of a protocol designed to address the critical section problem in operating systems?
- To increase the number of critical sections in the operating system.
- To ensure that no process ever enters the critical section.
- To allow multiple processes to freely access and modify shared variables.
- To design an algorithm that guarantees mutual exclusion in critical sections. (correct)
What is the significance of the Mutual Exclusion requirement in the critical-section problem?
What is the significance of the Mutual Exclusion requirement in the critical-section problem?
- It ensures that only one process at a time can be executing in its critical section. (correct)
- It removes the need for processes to ask for permission before entering critical sections.
- It allows multiple processes to execute simultaneously in their critical sections.
- It guarantees that all processes enter their critical sections at the same time.
