II. Consider a disk shown with a sector size of 1024 bytes, 1,000 tracks per surface, 100 sectors per track, 6 single-sided platters and a block size of 2,048 bytes. Suppose that a file containing 500,000 records of 110 bytes each is to be stored on such a disk and that no record is allowed to span two blocks. [3 Marks] a) How many records fit onto a single track? b) How many sectors are required to store the entire.file? If the file is arranged sequentially (contiguously- according to the 'next block concept') on disk, how many cylinders are needed
