Question 15

Consider allocation of memory to a new process. Assume that none of the existing holes in the memory will exactly fit the process’s memory requirement. Hence, a new hole of smaller size will be created if allocation is made in any of the existing holes. Which one of the following statements is TRUE?

A
The hole created by worst fit is always larger than the hole created by first fit.
B
The hole created by best fit is never larger than the hole created by first fit.
C
The hole created by first fit is always larger than the hole created by next fit.
D
The hole created by next fit is never larger than the hole created by best fit.
Question 15 Explanation: 
The size of hole created using best fit is never greater than size created by first fit. The best fit chooses the smallest available partition to fit the size of the process. Whereas, first fit and next fit doesn’t consider the size of the holes available.
Correct Answer: B
Question 15 Explanation: 
The size of hole created using best fit is never greater than size created by first fit. The best fit chooses the smallest available partition to fit the size of the process. Whereas, first fit and next fit doesn’t consider the size of the holes available.
