WebJul 9, 2024 · The real challenge of efficiently managing memory is seen in the case of a system which has multiple processes running at the same time. Since primary memory can be space-multiplexed, the memory manager can allocate a portion of primary memory to each process for its own use. However, the memory manager must keep track of which …

Follow the steps below to solve the problem: Initialize a variable, say count as 0 that stores the minimum number of bins required.; Sort the given array weight[] in …
WebUsing First Fit algorithm. Let's see, how first fit algorithm works on this problem. 1. 25 K requirement. The algorithm scans the list until it gets first hole which should be big enough to satisfy the request of 25 K. it gets the space in the second partition which is free hence it allocates 25 K out of 75 K to the process and the remaining 50 ... WebFeb 22, 2024 · First fit is a straight and fast algorithm, but tends to cut a large portion of free parts into small pieces due to which, processes that need a large portion of memory block would not get anything even if the sum of all small pieces is greater than it required which is so-called external fragmentation problem.
