Consider six memory partitions of size 200 KB, 400 KB, 600 KB, 500 KB,...
Best fit allocates the smallest block among those that are large enough for the new process. So the memory blocks are allocated in below order.
357 ---> 400
210 ---> 250
468 ---> 500
491 ---> 600
Sot the remaining blocks are of 200 KB and 300 KB
357 ---> 400
210 ---> 250
468 ---> 500
491 ---> 600
Sot the remaining blocks are of 200 KB and 300 KB

Best Fit Memory Allocation Algorithm
Heading: Introduction
The best fit algorithm is a memory allocation strategy that allocates the smallest available partition that is big enough to fit the process. It searches the entire memory partition list to find the partition that is closest in size to the process.
Heading: Given Data
The given memory partitions are:
- 200 KB
- 400 KB
- 600 KB
- 500 KB
- 300 KB
- 250 KB
The given processes and their sizes are:
- Process 1: 357 KB
- Process 2: 210 KB
- Process 3: 468 KB
- Process 4: 491 KB
Heading: Best Fit Algorithm Solution
1. Process 1 requires a partition of size 357 KB. The best fit partition for this process is 400 KB.
2. Process 2 requires a partition of size 210 KB. The best fit partition for this process is 250 KB.
3. Process 3 requires a partition of size 468 KB. The best fit partition for this process is 500 KB.
4. Process 4 requires a partition of size 491 KB. The best fit partition for this process is 600 KB.
Heading: Unallocated Partitions
The following partitions are not allotted to any process:
- 200 KB
- 300 KB
Heading: Explanation
The best fit algorithm searches for the smallest available partition that is big enough to fit the process. In this case, the 200 KB partition is too small for any of the processes, and the 300 KB partition is not big enough to fit the largest process, which is 491 KB. Therefore, these partitions are not allocated to any process.
Heading: Conclusion
In conclusion, the best fit algorithm allocates the smallest available partition that is big enough to fit the process. The unallocated partitions in this case are 200 KB and 300 KB.

Therefore, these partitions are not allocated to any process.
Heading: Conclusion
In conclusion, the best fit algorithm allocates the smallest available partition that is big enough to fit the process. The unallocated partitions in this case are 200 KB and 300 KB.
