Homework Answers
First Fit
In case of first fit we allocate the first free partition that is large enough to store the process.
Advantage
It is the Fastest algorithm because it searches as early as possible.
Disadvantage
In the end the unused memories left after allocation become waste. Thus it request for larger memory cannot be fulfilled.
Best Fit
In case of best fit we allocate the smallest free partition which meets the requirement of the process. This algorithm first searches the entire list and find the smallest portion that is enough to store the process .
Advantage
Memory utilization is optimized than first fit because it searches the smallest free partition first available.
Disadvantage
It is slower then the others because it need to travel the whole list to find the best position.

4. Worst-fit is an allocation algorithm that allocates the largest free block to a new job. It is the opposite of the best-fit algorithm. Using the following configuration with jobs arriving in order (Job A, B, C, D) and with blocks shown in order from low order memory to high order memory: Job List: Memory Block List: Job Number Memory Requested Memory Block Memory Block Size Job A 44K Block 1 250K Job B 220K Block 2 900K Job C...

Discuss the advantages and disadvantages of a gather society and an agrarian society in regard to their reliance on plant materials. Do not just repeat what was discussed in class, think about some other possibilities as well (there are more I did not mention in class this week that will come up through the semester. Be sure to address BOTH the advantages and disadvantages for BOTH types of society. Note that an advantage to one group may not be a...

Memory Allocation a) Is it possible to have both internal and external fragmentation with fixed partition memory allocation? How about with dynamic/variable memory partition allocation? Explain. (1 point) b) Suppose we have 1000K of memory where the first 100K is reserved. Also suppose that the following processes have been allocated memory in the following order: P1: 100K, P2: 100K, P3: 25K, P4: 200K, P5: 200K, P6: 75K, P7: 100K. Create a diagram of memory. Suppose that P2, P4, and P6...
