Web14 jan. 2024 · (1) It increases the degree of multiprogramming (2) Allow address spaces to be shared by several processes so that multiprogramming increased. [Statement (1) correct] [Statement 2 wrong] (3) Context switching occurs frequently between main memory and disk by swap-in and swap-out so context switching increases. [Statement 3 wrong] Webdegree of multiprogramming (no. of processes in memory at a time). If the degree of multiprogramming is to be kept stable (say 10 processes at a time), then the long-term scheduler may only need to be invoked when a process finishes execution. The long-term scheduler must select a good process mix of I/O-bound and processor bound processes.
Web23 jun. 2010 · Causes of Thrashing. It result in severe performance problems. 1) If CPU utilization is too low then we increase the degree of multiprogramming by introducing a new process to the system. A global page replacement algorithm is used. The CPU scheduler sees the decreasing CPU utilization and increases the degree of … WebA multitasking operating system enables the execution of two or more programs at the same time. The operating system accomplishes this by shifting each program into and …
