53. Consider a file currently consisting of 50 blocks. Assume that the file control block and the index block is already in memory. If a block is added at the end (and the block information to be added is stored in memory), then how many disk I/O operations are required for indexed (single-level) allocation strategy?

  • Option : A
  • Explanation :
    According to question file control block and the index block is already in memory. So, we don't need to transfer them from anywhere else for further operation. If a block is added at the end (and the block information to be added is stored in memory), this is a single operation. So we need only one I/O operation required for indexed (single-level) allocation strategy. So, option (A) is correct.
