MadeEasy Test Series: Operating System - Process Synchronization
The definition of progress is: When no process is in the critical section and another process wants to enter the critical section, then it should be allowed without any delay Suppose we do a context switch from 1 ... critical section, the second process is unable to enter the critical section. How does this achieve progress then?
