FAT

FAT, or File Allocation Table, is a system used by computers to keep track of where files are stored on a storage device like a USB drive or memory card. Think of it as an index or map that records the locations of all parts of each file. When you open a file, the FAT helps the computer find all its pieces quickly. It also manages space efficiently by marking areas as used or free, preventing data from overlapping. Overall, FAT ensures data is organized and easily accessible for the computer to read and write files.
