Critical Sections: Select all of the following statements that are true. A critical section is a segment of code in which a process has write-access to data or resources that are shared with at least one other process. In a system consisting of n processes, a critical section can be entered by more than one of these n processes at a time. In order to protect critical sections, race conditions are used in a process to request permission to enter its critical section. A process that is currently not executing in its critical section must not prevent other processes to enter the critical section. Every process waiting at the entrance of a critical section must be allowed to enter this section at some point. No eternal waiting must be possible. Mutual blocking is one method to decide which process may enter the critical section first.
