Suppose we have variable logical records of lengths of $5$ bytes, $10$ bytes and $25$ bytes while the physical block size in disk is $15$ bytes. What is the maximum and minimum fragmentation seen in bytes?
Answer : option D
please refer this link for checking solution: http://nptel.ac.in/courses/106108101/pdf/Worked_Out_Problems/Mod_2.pdf
Question no 2.4 in the above pdf
Now we have Logoical Records of 5B , 10 B and 25 B
assuming that records are spanned .
saY record 1= 5B
Recorrd 2= 10B
Record 3= 25B
Minimum amount of fragmentation will happen if i allocate record in R1R2R3. each will give mInimum Fragmentation value OF 5
Max amount of fragmentation will happen if i allocate record in R1R2R3OR R2R1R3. each will give mAX Fragmentation value OF 10
hence 10 and 5 will be answer ---Option d
