What Is Best Fit Allocation?

Best-fit allocation is a memory management strategy used in computer operating systems to allocate memory resources to processes. The OS finds the smallest available memory block that can accommodate the process being allocated, i.e., the best-fit algorithm looks for the memory block closest in size to the requested process size. The algorithm aims to minimize memory wasting by allocating the smallest possible memory block to each process. However, it can be slower than other allocation algorithms because it must search through the entire list of available memory blocks to find the best fit.
