FAT

File Allocation Table

Allocates space on the disk for files, one cluster at a time; locks out unusable clusters; identifies unused (free) area; and lists a files' location. With two FATs present, the second copy ensures consistency and protects against loss of data if one of the sectors on the first FAT is damaged. Most FATs are 16 bit, Microsoft has created a newer 32-bit FAT which has been incorporated into the newer OS's, starting from Windows 95 OSR2.
