The two methods of managing free space on the inode-based system are:
- Linked List of free blocks – the pointers are stored in the free blocks themselves, only a block of
pointers needs to be kept in main memory. Advantageous in that it gets smaller as the disk is used up.
- Bitmap Allocation – individual bits in a bit vector flags used and free blocks, but is large and of a fixed
size as it corresponds to the entire disk (perhaps too large to hold in main memory) and expensive to
search. However, it's simple to find contiguous free space.
