Best Fit

Best Fit is a memory allocation method used by computers to assign programs or data to available memory spaces. When a program needs memory, Best Fit searches for the smallest free memory block that is large enough to hold it, aiming to minimize wasted space. Think of it like shopping for a storage unit: you pick the smallest available unit that still fits your needs, so no space is wasted. This approach helps use memory efficiently, reducing leftover unused space, although it might take more time to find the perfect match than other methods.
