Answer:
True.
Explanation:
For all the count values, if Ranfun() returns true then all the values of count would be printed. Then the sequence of count values printed would be 1 2 3 4 5. Also for all the values of count if Ranfun() returns false then all the values would be enqueued. When we try to dequeue elements from queue we would get them in the same order of their entry into the queue. Thus, the sequence would be 1 2 3 4 5. Hence, we can say that this output sequence is possible. TRUE.
Answer:
Answer is option (a) It includes data that has changed since the last full backup.
Explanation:
Differential Backup is a method used in Database Management Systems (DBMS) in which it includes the data (copies of all the files) that has changed (either created or updated or altered) since the last full backup. If it is a partial backup instead of full backup, then it is not a differential backup method as many files might have changed. Option (b) is false as the backup has to be a full backup not an incremental backup. Option (c) is false as the backup has to be a full backup ( not just a backup ), Option (d) is false as only the files that are changed is stored not the whole database since a full backup.
