What are the properties which a data item should possess to implement a critical section?

The Critical Section Problem Solution should satisfy the following conditions:

1. Mutual Exclusion: If process Pi is executing into its critical section, so no other processes can be executing into their critical sections.

2. Progress: If no process is executing into its critical section and there exist several processes which need to enter their critical section, so the selection of the processes which will enter the critical section subsequently cannot be postponed indefinitely.

3. Bounded Waiting: A bound should exist on the number of times that other processes are permitted to enter their critical sections after a process has done a request to enter its critical section and before which request is granted.

-Suppose that each process executes at a non-zero speed

-No assumption relating to concern speed of the n processes.
