Rank the algorithms in terms of how efficiently they use memory. first fit: 115 -> 300 500-> 600 358 -> 750 WebThere are four main types of memory management algorithms: best-fit, first-fit, next-fit, and worst-fit. Best-fit is a memory management algorithm that attempts to assign memory to jobs in the most efficient way possible. This algorithm searches through all available memory partitions, and assigns the job to the partition that best fits its size.

WebWorst fit:The memory manager places a process in the largest block of unallocated memory available. The idea is that this placement will create the largest hold after the allocations, … WebThe results of the simulation of the three methods show that the efficiency of next-fit is decidedly inferior to first-fit and best-fit when the mean size of the block requested is less than about 1/16 the total memory available. Beyond this point all three allocation schemes have similar efficiencies. References 1 Knuth, D.E. buck wild country dance club webster tx
