What is the Best Fit Algorithm for Memory Partitions?

1. If you had 10, 50, 20, 30, and 60 KB in order and wanted to work with these incoming processes 21, 47, 5, 45 KB find the best fit.


3. I know how to do 21 and 5 but for 47 and 45 I'm confused. Best fit says to produce the smallest left over hole. So, would I put 47 in 60 because it's smaller than 45 in 60?
(21 would go into 30 and 5 would go into 10)

Best fit operates on the incoming processes one at at time, in the incoming order. There's no look ahead involved. For each process, best fit means to choose the smallest memory partition that the process will fit into.
