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.
