Progress If no process is executing in its critical section and some processes wish to enter their critical sections, then Only those processes that are waiting to enter can participate in the competition (to enter their critical sections). No other process can influence this decision. This decision cannot be postponed indefinitely. 12
Bounded Waiting After a process made a request to enter its critical section and before it is granted the permission to enter, there exists a bound on the number of times that other processes are allowed to enter. Hence, even though a process may be blocked by other waiting processes, it will not be waiting forever. 13
