What is priority scheduling algorithm?
The priority scheduling algorithm is a kind of CPU scheduling algorithm where the processes that wait for the CPU are scheduled according to their priority..
What is the difference between preemptive and non preemptive scheduling?
1.) in preemptive scheduling we prempt the currently executing process, in non preemptive scheduling we allow the current process to finish its CPU burst time... 2.) in preemptive scheduling the process is forcibly sent to waiting state when a process with higher priority comes to CPU, in non preeemptive scheduling the process at running state can not be forced to leave the CPU until it completes........
Advantages of Round Robin Scheduling?
It is the most simple scheduling algorithmn It is easy to implement in software If the processes are of varied length then it becomes slow.

What are the differences between cscan and scan algorithms for disk scheduling?
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.

What is the efficiency of the C scan algorithm for disk scheduling?
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.
Why do you use disk scheduling in operating systems?
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.

What is the disk scheduling in ms dos?
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.

What type of scheduling is there in RTOS?
A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.
What is the meaning of sequential scheduling?
It means scheduling one after another.
What is stream scheduling?
Stream Scheduling is a scheduling system where there is a steady stream/flow of patients at set appointments throughout the day.
