Let's say there are seven requests: 16, 24, 43, 82, 140, 170, and 190. Additionally, the disc arm is supposed to travel "towards the larger number" while the read/write arm is at 50. What is the total seek time?
Correct answer is '332'. Can you explain this answer?
Verified Answer
Lets say there are seven requests: 16, 24, 43, 82, 140, 170, and 190. ...
The given data,
"towards the larger number
" means it works like a scan algorithm.
Let's say there are seven requests: 16, 24, 43, 82, 140, 170, and 190.
The read/write arm is at 50.
" means it works like a scan algorithm.
Let's say there are seven requests: 16, 24, 43, 82, 140, 170, and 190.
The read/write arm is at 50.
The seek time is calculated as:
=(199-50)+(199-16)
=332
=(199-50)+(199-16)
=332
Hence the correct answer is 332.

Lets say there are seven requests: 16, 24, 43, 82, 140, 170, and 190. ...
In one direction only. In this case, the disc arm will start at a certain position and move towards the nearest request in that direction. Once it reaches that request, it will continue in the same direction to the next closest request.
To determine the total distance traveled by the disc arm, we need to know the starting position of the disc arm. Let's assume the starting position is 50.
Here is the order in which the requests will be serviced and the distance traveled at each step:
1. Start at position 50.
Distance traveled: 0 (since the arm is already at the starting position)
2. Move to request 43.
Distance traveled: 7 (from 50 to 43)
3. Move to request 24.
Distance traveled: 19 (from 43 to 24)
4. Move to request 16.
Distance traveled: 8 (from 24 to 16)
5. Move to request 82.
Distance traveled: 66 (from 16 to 82)
6. Move to request 140.
Distance traveled: 58 (from 82 to 140)
7. Move to request 170.
Distance traveled: 30 (from 140 to 170)
8. Move to request 190.
Distance traveled: 20 (from 170 to 190)
Total distance traveled by the disc arm: 208 units.
