14. Capacity of this Medium

• FAT12 allocates 12 bits per FAT entry

  • Limits addressing to 4,096 (212) clusters

• This (removable) device is configured so that:

  • 1 cluster = 1 sector

  • 1 sector = 512 B

• This FAT12 table is limited in capacity to 2,097,152 bytes (2 MB)

  • I.e., 4K clusters of 512 B each

• This device has 2,880 sectors

  • 512 B clusters yields a device capacity of 1.44 MB

  • Corresponds to what we would expect for a floppy
