Concept:
Free space management:
For the purpose of assigning space to newly generated files, the system maintains track of the free disc blocks. Additionally, managing free space becomes essential in order to utilize the space made available by removing the files. The disc blocks that are not assigned to any files or directories are tracked by the system in a list called free space.

Free space management is implemented mainly as:
- Bitmap or Bit vector
- Linked List
- Grouping
- Counting
- Space Maps
Paging is a memory management strategy that avoids the necessity for contiguous physical memory allocation. This approach allows a process's physical address space to be non-contiguous.
Hence the correct answer is Paging.
Hence the correct answer is Paging.

Free Space Management Techniques
Bitmap or Bit vector:
- In this technique, each block of free space is represented by a bit in a bitmap.
- If the bit is 1, it means the block is free; if it is 0, the block is allocated.
- This method is efficient for quickly finding free blocks but can be memory-intensive for large storage systems.
Counting:
- This technique involves keeping track of the number of free blocks in a specific range.
- It requires maintaining a count of free blocks, which may be updated whenever a block is allocated or deallocated.
- Counting can provide a quick way to determine available space but may not be as efficient as other methods for large storage systems.
Paging:
- Paging is not typically used for free space management but rather for memory management in virtual memory systems.
- It involves dividing memory into fixed-size blocks called pages and managing these pages for efficient memory allocation.
- While paging can help optimize memory usage, it is not directly related to free space management in storage systems.
Grouping:
- Grouping is a technique where free blocks are organized into groups or clusters based on their physical location.
- This method can help optimize disk access and improve performance by grouping related blocks together.
- Grouping is not as commonly used as bitmap or counting for free space management but can be beneficial in certain storage systems.
