a) Mutual exclusion: If a process is implementing in the critical section, then no other process is able to be executed in the critical section.
b) Progress: If no process is implementing in the critical section and there are processes that wish to enter the critical section, after that only those process that are not executing in the non critical section can participate in the decision of which will enter its critical section next, and this section cannot be postponed indefinitely
c) Bounded waiting: There subsist abound on the number of times that other processes are permitted to enter their critical sections after a process has made a request to enter its critical section and before that request is granted. This bound avoid starvation of any single process.
Now, let us discuss two related algorithms for deciding which pages to evict. The clock algorithm is one of the most popular choices. It works by keeping frames in a circular struc
