Explain the concept of 'Progress' in the context of critical sections.
Explain the concept of 'Progress' in the context of critical sections.
If no process is executing in its critical section and there exist some processes that wish to enter their critical section, then the selection of the process that will enter the critical section next cannot be postponed indefinitely.

What does 'Bounded Waiting' mean in the context of critical sections?
A bound must exist on the number of times that other processes are allowed to enter their critical sections after a process has made a request to enter its critical section and before that request is granted.
