Disk Organisation

Size of a file is variable - the need for dynamic space management
Generally, space is allocated in blocks (typically 512, 1024 or 2048 bytes)

Since a disk is composed of blocks, and files are translated into these blocks, how is this structure actually implemented ?

 
• Block Linkage or Chaining
• File Allocation Table (FAT)
• Index Blocks
• Criteria for choosing Disk Block Size
• Management of free space
