What are the different types of semaphore? Principally the semaphore is able to be classified into two on the basis of their values a) Counting semaphore: In counting s
Worst Fit Algorithm Here we obtain the largest space available for the smallest. Therefore after that process entered there will be much more space remaining. In this space we
LRU approximation page replacement In this we are able to use the reference bit associated with the page entry to choose a page to be removed. The various algorithms used for
Since most of the programs require a lot of memory allocation/deallocation, we expect the memory management to be fast, to have low fragmentation, make good use of locality, and be
Define lazy swapper. Rather than swapping the entire process into main memory, a lazy swapper is used. A lazy swapper never swaps a page into memory unless that page will be ne
Problem: a) Define a ‘file' and list the objectives of the file management system. b) List the ways in which programs access files and determine for what file types you woul
