What does the acronym FAT stand for in computer storage?

The acronym FAT stands for File Allocation Table. This is a type of file system that was developed by Microsoft for managing data on disk drives. The main purpose of the File Allocation Table is to keep track of which areas of the storage device are allocated for files and which areas are free.

When a file is saved on a disk, the FAT system records where the file's data is located, allowing the operating system to efficiently read the file when requested. The FAT structure helps manage the storage space effectively by maintaining a mapping of file clusters on the disk.

Understanding the FAT system is crucial in computer applications and information technology, as it is foundational to how file systems operate, particularly in older systems and some modern embedded devices. This knowledge provides insight into storage efficiency and file management practices.
