Galvin Edition 9 Exercise 11 Question 14 (Page No. 540)

Question

If the operating system knew that a certain application was going
to access file data in a sequential manner, how could it exploit this
information to improve performance?

Answer 1

When a block is accessed, the file system could prefetch the subsequent blocks in anticipation of future requests to these blocks. This prefetching optimization would reduce the waiting time experienced by the process for future requests.
