Long term schedular controls the degree of multiprogrammingExplain?
hi, Work of long term schedular is to admit new process to ready queue(forked() or program form disk ). Multiporgramming means having more than one processes in the memory(RAM) at a same time(may not be executing). so as long term scheduler brings new processes into the memmory we can say it controlls the degree(#process in RAM) of multiprogramming.
What are short long and medium term scheduling?
Long term scheduler determines which programs are admitted to the system for processing. It controls the degree of multiprogramming. Once admitted, a job becomes a process.Medium term scheduling is part of the swapping function. This relates to processes that are in a blocked or suspended state. They are swapped out of real-memory until they are ready to execute. The swapping-in decision is based on memory-management criteria.Short term scheduler, also know as a dispatcher executes most frequently, and makes the finest-grained decision of which process should execute next. This scheduler is invoked whenever an event occurs. It may lead to interruption of one process by preemption.
What is Degree of Multiprogramming?
number of process in system number of threads in a program..
What are the difference between long term scheduler and medium term scheduler?
buhat mo ug assignment ..ayaw mo pagsalig dire, sa POS ni noh, isumbong tamo ni mam Trigo.hahaha SAKPAN, pero atik rah, panghatag pud mo answer hah ~abalorz bastah mao ni......

Is the Process Scheduler is also called the high-level scheduler?
No. The Job Scheduler is the high-level scheduler.
What is Trashing in operating system?
Trashing means excessive page input output in swapping. Which reduces the degree of multiprogramming.
Is windows operating system multiprogramming or multitasking?
multiprogramming
When was THE multiprogramming system created?
THE multiprogramming system was created in 1968.
What is job scheduler and dispatcher?
What is job scheduler and dispatcher?
What is the difference between the job scheduler the CPU scheduler?
1. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. 2. Job scheduler selects the processes from the job pool and load them in to the memory for execution. in other hand CPU scheduler selects among the processes that are in ready to execute and allocate the CPU to one of them. 3. CPU scheduler is faster than the process scheduler.
Discuss the effect of heavily multiprogramming on demand page swapping?
Mutiprogramming helps increase the CPU utilization to some extent, but if the degree of Multiprogramming is increased above a certain limit (i.e Heavy Multiprogramming) it can lead to Thrashing and thus decrease the CPU utilization drastically.Heavy Multiprogramming may lead to Thrashing, a condition where a system is spending more time Page Faulting (i.e swapping pages in and out of memory) rather than executing them, this leads to deterioration of system performance.
Is multitasking a logical extension of multiprogramming?
timesharing is logical extention of multiprogramming.
