  1. Given below an example of memory configuration after a number of placement and swapping-out operations. Show the location of new allocation using first-fit, next-fit and worst-fit placement algorithms in satisfying the following allocation requests:
    1. 10M.
    2. 15M.

Allocated block

Free block

4M

12M

16M

8M

   14M

20M

Last allocated block (4M)

I have completed this problem Please give thumbs up if you like it

Let us first discuss about First Fit ,Best Fit and Next Fit

Step 1

First Fit :- Allocate the process in s partition which is first sufficient partition from the top of memory

Worst Fit : Allocate the process in a condition which is largest sufficient among the free available partition

-> To find out largest sufficient, it required to search all the free partition in the memory

Next Fit : It also works like First Fit but it will search for first sufficient partition from last Allocation point

Step 2
