The correct matching of the following pairs is
(A) Disk check (1) Roundrobin (B) Batch processing (2) Scan (C) Time sharing (3) LIFO (D) Stack operation (4) FIFO
A B C D 3 4 2 1
A B C D 4 3 2 1
A B C D 3 4 1 2
A B C D 2 4 1 3
Explanation: Option (D) is correct:
A: Disk check- (2) Various scan algorithms are used for disc checking like FCFS, SSTF, SCAN, C-SCAN, LOOK, C-LOOK etc.
B: Batch Processing- In batch processing processes are strictly executed in FIFO order.
C: Time sharing- In Round Robin scheduling algorithm, the processes perform CPU execution in time sharing manner as there is a fixed time quanta associated with each process for execution.
D: Stack operation- stack operates in last in first out manner.
