Operating System Questions
The file allocation table (FAT) is a data structure used by file systems to keep track of the allocation status of each cluster or block on a storage device. It serves as a map or index that allows the operating system to locate and access files stored on the disk. The FAT contains information about which clusters are free, allocated, or reserved for system use. It helps in organizing and managing files, ensuring efficient storage utilization, and facilitating file retrieval and modification operations.
