Frequently Asked Questions on Seek Time

What is seek time in the context of operating systems?

A disk is divided into many circular tracks. Seek Time is defined as the time required by the read/write head to move from one track to another

How does seek time impact the overall performance of a disk system?

Lower seek times result in faster data access, enhancing the efficiency of input and output operations.

What factors contribute to seek time?

Seek time is influenced by various factors, including the mechanical properties of the disk drive, the distance the arm must travel, and the speed at which the arm can move.

Are there strategies or algorithms to optimize seek time?

Yes, disk scheduling algorithms like FCFS, SCAN, C-SCAN, C-LOOK and LOOK are designed to minimize seek time.


Seek Time in OS

Seek Time is one of the key components of Disk Scheduling, Before going to Seek Time, let’s first discuss Disk Scheduling. Disk Scheduling is done by operating systems to schedule I/O requests arriving for the disk. Disk scheduling is also known as I/O Scheduling. Multiple I/O requests may arrive by different processes and only one I/O request can be served at a time by the disk controller. Thus other I/O requests need to wait in the waiting queue and need to be scheduled.

Gate Question

Consider a disk pack with a seek time of 4 milliseconds and rotational speed of 10000 rotations per minute (RPM). It has 600 sectors per track and each sector can store 512 bytes of data. Consider a file stored in the disk. The file contains 2000 sectors. Assume that every sector access necessitates a seek, and the average rotational latency for accessing each sector is half of the time for one complete rotation. The total time (in milliseconds) needed to read the entire file is _________. (A) 14020 (B) 14000 (C) 25030 (D) 15000 [GATE CS 2015]...
