1. Given memory partitions of 100 KB, 500 KB, 200 KB, 300 KB and 600 KB (in order), how would each of the first-fit, best-fit and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB and 426 KB (in that order)? Which algorithm makes the most efficient use of memory?
Homework Answers
First-fit will be 212K is put in 500K partition, 417K is put in 600K partition, 112K is put in 288K partition (new partition 288K = 500K - 212K), 426K must wait Best-fit will be 212K is put in 300K partition, 417K is put in 500K partition, 112K is put in 200K partition, 426K is put in 600K partition Worst-fit will be 212K is put in 600K partition, 417K is put in 500K partition,112K is put in 388K partition, 426K must wait

Given five memory partitions of 100 KB, 300 KB, 200 KB, 500 KB, and 400 KB (in order), how would each of the first-fit, best-fit, and worst-fit algorithms place processes of 200 KB, 417 KB, 100 KB, 350 KB and 100 KB (arriving in order)? Be sure and discuss the differences in the placement in terms of memory usage.(If someone is capable of dumbing it down for me, I would greatly appreciate it.)
