The optimal replacement policy, called OPT, is to evict the page which will be accessed farthest into the future. Since we can't predict the future precisely, we can't implement OPT in any real system. We can, however, run OPT on a saved trace of memory accesses, to measure how our real algorithm compares with OPT for a given trace.
Explain the various page replacement strategies. Page replacement-basic scheme with diagram Optimal page replacement LRU page replacement FIFO page replacement LRU
What are interrupts? Interrupts are in some ways the mainly "famous" system resources, ever since almost everyone who's used a computer has heard of them even if they don't k
Many-to-Many Model The many-to-many model- many user-level threads to many kernel-level threads avoids several of the limitations of the one-to-one model, although extending mu
Explain about paging? Answer: Paging is a memory-management scheme that permits the physical-address space of process to be noncontiguous. Paging avoids the considerable proble
explain how response time are reduced by allowing time sharing on top of multiprogramming
Explain the Per Thread Scoping Thread-level programming introduces new twists for application-level variable scoping. Threads are commonly used in one of two ways. To ex
Conservative GC can be used for languages such as C and C++, which were not explicitly designed for garbage collection. This is a non-copying technique. A conservative garbage coll
Can a direct access file be read sequentially? Explain. Yes. Keep a counter, cp, initially set to 0. After reading record cp, increment cp.
What is a Dispatcher? The dispatcher is the module that gives control of the CPU to the process selected by the short- term scheduler. This function includes: Switching
How exactly is a page table used to look up an address? The CPU has a page table base register (PTBR)which points to the base (entry 0) of the level-0 page table. Each process h
