Question
Consider a file system on a disk that has both logical and physical block sizes
of 512 bytes. Assume that the information about each file is al ready in
memory. For each of the three allocation strategies (contiguous, linked, and
indexed), answer these questions:
a. How is the logical-to-physical address mapping accomplished in this
system? (For the indexed allocation, assume that a file is always less than
512 blocks long.)
b. If we are currently at logical block 10 (the last block accessed was block
10) and want to access logical block 4, how many physical blocks must be
read from the disk
