Synchronization Flashcards
If a process is executing in its critical sections. then no others processes can be executing in their critical section. This condition is called
a/ critical section
b/ Synchronous exclusion
c/ Asynchronous exclusion
d/ Mutual exclusion
e/ None of the mentioned
d/ Mutual exclusion
Why does it need Synchronisation in OS?
a/ Prevent computer cash
b/ Prevent file corrupt
c/ Prevent race conditions from happening
d/ Prevent hardware broken
e/ None of the mentioned above
