To Implement Disk Scheduling Algorithms

Pre Test

1. Which of the following is the primary function of a disk scheduling algorithm?

a) Organizing data on the disk for efficient storage.
b) Managing the flow of data between the CPU and memory.
c) Optimizing the order in which disk requests are served.
d) Allocating disk space to different files and programs.

2. What does the term "seek time" refer to in disk access?

a) The time taken to transfer data between the disk and memory.
b) The time taken to locate the desired sector on the disk.
c) The time taken to position the disk head over the correct track.
d) The time taken to read or write data to the disk.

3. Which of these algorithms is NOT a common disk scheduling technique?

a) Shortest Seek Time First (SSTF)
b) SCAN
c) FIFO (First In First Out)
d) Priority Based Scheduling

4. What is the main disadvantage of the FCFS disk scheduling algorithm?

a) It can lead to excessive disk head movement.
b) It prioritizes the shortest seek time, ignoring other factors.
c) It is highly complex and resource-intensive.
d) It does not consider the order of requests.

5. What is the primary goal of disk scheduling algorithms?

a) Increase disk access time
b) Decrease disk access time
c) Maximize disk space utilization
d) Improve CPU utilization
