Question

The following three conditions must be satisfied to solve the critical section problem : (choose three)

a) Aging
b) Mutual Exclusion
c) Deadlock
d) Progress
e) Bounded Waiting

Answer 1

To solve the critical section problem, the three main conditions that must be met are Mutual Exclusion, Progress, and Bounded Waiting. These ensure that processes access the critical section without conflicts and with fairness.

Step-by-step explanation:

To solve the critical section problem in concurrent or multi-threading programming environments, three primary conditions must be met:

1. Mutual Exclusion - This condition means that only one process can be in its critical section at a time. No two processes should be allowed to execute in their critical sections simultaneously to avoid conflicts over shared resources.
2. Progress - The progress condition ensures that the process selection for entry to the critical section cannot be postponed indefinitely. If there is a process that needs to access the critical section, the algorithm must ensure that eventually, the process will be allowed to enter its critical section.
3. Bounded Waiting - This condition limits the number of times other processes are allowed to enter their critical section after a process has requested to enter its critical section and before the request is granted. It prevents starvation by ensuring that there is a bound or limit on the waiting time.

Conditions like deadlock and aging are related to issues that can occur in systems that deal with concurrent processes but do not directly correspond to the fundamental conditions that must be met to solve the critical section problem. Such issues need to be addressed through other mechanisms in the design of concurrent systems.
