why we use disk scheduling in c ?
The main difference between the C-SCAN and SCAN algorithms for disk scheduling is how they handle requests that are located at the end of the disk. C-SCAN moves the disk arm to the other end of the disk after servicing the last request, while SCAN moves the arm back to the beginning of the disk. This difference affects the order in which requests are serviced and can impact the overall efficiency of the disk scheduling algorithm.

>File systems must be accessed in an efficient manner >As a computer deals with multiple processors over a period of time, a list of request to access the disk build up >The operating system uses a disk scheduling technique to determine which request to satisfy.

The efficiency of the C-scan algorithm for disk scheduling is considered to be high. It is a variant of the scan algorithm that improves performance by reducing the seek time of the disk arm. The C-scan algorithm scans the disk in one direction only, which can lead to faster access times compared to other algorithms.
Disk Scheduling and Task Scheduler and different terms. Disk Scheduling: Input / Output Scheduling or I/O Scheduling is a term used to describe the method computer operating systems decide the order that block I/O. Task Scheduler: Task Scheduler is a component of Microsoft Windows that provides the ability to schedule the launch of programs or scripts at pre-defined times or after specified time intervals. It was first introduced in the Windows 95 Plus! pack as System Agent [1] but was renamed to Task Scheduler in Windows 98. The Windows Event Log service must be running before the Task Scheduler starts up.

Changing the structure of a file may or may not affect the fragmentation of the disk. But, in most cases, the computer is going to store the file in the same location after the change.

Its regarding disk scheduling in any OS..When a process wants to do disk I/O, it makes a call to the operating system. Since the operation may take some time, the process is put into a blocked state, and the I/O request is sent to a part of the OS called a device driver. If the disk is idle, the operation can be started right away, but if the disk is busy servicing another request, it must be added to a queue of requests and wait its turn. Thus the total delay seen by the process has several components:The overhead of getting into and out of the OS, and the time the OS spends fiddling with queues, etc.The queuing time spent waiting for the disk to become available.The latency spent waiting for the disk to get the right track and sector.The transfer time spent actually reading or writing the data.
