20: ---------------keep in memory only those instructions and data that are needed at any given time. Ans= Overlays 21: If the system can allocate resources to each process in some order and still avoid a deadlock then it is said to be in _________ state. Ans= Safe 22: A condition where a set of blocked processes each holding a resource and waiting to acquire a resource held by another process in the set is termed as ________.

Ans= Deadlock (This MCQ appeared twice in the exam)
