What are the 4 basic methods of organizing files on a disk?

The four basic methods of organizing files on a disk are:

1. File Allocation Table (FAT): This method uses a table to keep track of the locations of files on the disk, allowing for efficient access and management.
2. Indexed Allocation: This approach creates an index block that contains pointers to the actual disk locations of file data, facilitating quick access and management of fragmented files.
3. Contiguous Allocation: In this method, files are stored in contiguous blocks, which enhances performance due to reduced seek time, but can lead to fragmentation over time.
4. Linked Allocation: This technique links blocks of a file using pointers, allowing for dynamic file growth, but may result in slower access times due to non-contiguous storage.
