WebA) critical section B) entry section C) mutex D) test-and-set C (atomicity) A solution to the critical section problem does not have to satisfy which of the following requirements? A) mutual exclusion B) progress C) atomicity D) bounded waiting True A nonpreemptive kernel is safe from race conditions on kernel data structures. True False WebThe critical-section problem is to design a protocol that the processes can use to synchronize their activity so as to cooperatively share data. Each process must request permission to enter its critical section. The section of code implementing this request is the entry section. The critical section may be followed by an exit section.
