WebNov 9, 2024 · There are two general approaches to waiting in operating systems: firstly, a process/task can continuously check for the condition to be satisfied while consuming the processor – busy waiting. Secondly, a process can wait without consuming the processor. In such a case, the process/task is alerted or awakened when the condition is satisfied. WebMar 20, 2024 · If you swap the lines, the bounded waiting condition would no longer exist. Proof. Suppose that only 1 process P(i) made the request to access Critical Section and it successfully entered. So . lock = true and waiting[i] = true because only then it would have been able to come out of the for loop.
