WebSimilar to the Best fit strategy, the entire Memory array has to be traversed to obtain the Worst fit Hole. As the name might suggest, its cons are plenty. First, the time taken to implement Worst fit is higher than that of First fit and Best fit strategies. Second, it's the least efficient strategy based on Memory Utilization. WebIn conclusion, memory management algorithms are used to manage the allocation of memory resources, such as physical RAM, virtual memory, and disk space. There are four main types of memory management algorithms: best-fit, first-fit, next-fit, and worst-fit. To write a C++ program that implements these four memory management algorithms, the …
