Windows XP supports only cooperative multitasking True or false?
False. Windows XP is a preemptive multitasking system. All contemporary operating systems are designed to use preemptive multitasking.
What are the relationships between priority and FCFS of CPU scheduling algorithms?
this is my doubt about the non-preemptive priority scheduling. i m doing bachelor of engineering in IT and this question in end semester exam. the question is as follows:Assume you have the following jobs to be executed with one processor, with the jobs arriving in the order listed here:Process Burst Time PriorityP1 80 5P2 20 1P3 10 3P4 20 2P5 50 4Suppose the system uses priority scheduling. Draw Gantt chart and calculate average waiting time for the processes.My doubt is:suppose if we were to use non-preemptive priority scheduling, the question says the jobs arriving in the order listed, so as per the order P1 will arrive first so it will get the CPU first and in non-preemptive once a job gets CPU it will not leave CPU till the process finishes, then as per the order P2 will come and same thing repeats.... so it acts like FCFS scheduling and priority is of no use here. But my lecturer says we have to follow the priority and P2 will come first, but the line the jobs arriving in the order listed is still not letting me agree with my lecturer. Can anyone help out?
Difference between preemptive and non preemptive?
if block Ki of size Ni is to be transferred to memory M1 & the blocks occupying the space in M1 can't be preempted by block Ki then it is necessaray to find or create a space of Ni words inM1 . this process is called non preemptive allocation....non preemptive allocation can't make efficient use of memory allocation.whenever preemptive allocation is used for efficient use of the available memory space and rellocation can be done.

How does RTOS determine the Time frame If suppose you are having an event with Highest priority and if its goes on to the Infinity loop how it handles this situation being deterministic in behavior?
There are different scheduling mechanisms that RTOSes can use to be deterministic. The most common is preemptive scheduling. In this model, each task has a relative priority. The highest priority task that is ready to run gets control of the processor. This is what provides deterministic behavior. When no task is ready to run the system will go to the idle loop. An RTOS is simply a tool to acheive a deterministic system. It is up to the developer to build a system that is capable of meeting its deadlines. A poorly designed system can encounter situations where important tasks do not get processor time because a higher priority task has not released.
Does Windows use a preemptive or cooperative type of multitasking?
Both. Windows 3.1 and earlier used cooperative multitasking. Windows 95 and later use preemptive multitasking.
Windows XP supports only cooperative multitasking True or false?
False. Windows XP is a preemptive multitasking system. All contemporary operating systems are designed to use preemptive multitasking.
What was the first multitasking distribution of windows?
Windows NT 3.1 was the first to use a preemptive multitasking. However, it was Windows 95 which had true multitasking.
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.

Which CPU scheduling Algorithm is used by Windows XP OS?
In the past (and perhaps currently as well) it has used round-robin, at one time 1 second but since updated to .1 seconds. It may also have other features such as preemptive abilities. Priority fair scheduling.
Did Thomas Hardy use the word 'preemptive' in any of his books?
My name is Thomas Hards. The answer is yes =].
What type of scheduling software is the easiest to use for medical offices?
The Medical Office Scheduler by SoftAid is the easiest scheduling software available for medical office. The package is full-service so cost depends on size of office and number of users. The company provides quotes upon request.
What is latence?
The time between when a thread is scheduled and when it begins to execute. Theoretically, in a preemptive OS the dispatch latency for a high-priority thread should be very low. However, in practice preemptive OSs are non-preemptive at times; for example, while running an interrupt handler. The duration of the longest possible non-preemptive interval is said to be the worst-case dispatch latency of an OS.
What CPU scheduling algorithm is used by?
same as linux use.
