Module 5: Memory Management

20247m

Given five memory partition of 100 KB, 500 KB, 200 KB, 300 KB, and 600 KB(in order), how would the first-fit and best-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)? Which algorithm makes the most efficient use of memory?

First-fit vs Best-fit partitions 100,500,200,300,600. Processes 212,417,112,426

First-fit: 212→500(288 left),417→600(183),112→288? Actually 500 left 288, so 112→288, 426→183 fail? Need 600 now 183, none → wait for 417? Detailed: 212→500,417→600,112→200,426→300 fails (300<426). So 426 waits.
Best-fit: 212→300(88),417→500(83),112→200? Actually 112→200(88) leaves, 426→600(174). Best-fit places all, more efficient. Best-fit uses memory better here.
