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 already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: (Explain How to Calculate)

Q - 1. If we are currently at logical block 12 (the last block accessed was block 12) and want to access logical block 3, how many physical blocks must be read from the disk?
