Sumario:The article examines the relationship between file systems and disks in computer science. Particular attention is given to how each reacts to an unplanned computer system crash, similar to what may occur during a power failure. The author notes that file systems typically return to a state it was in prior to the crash and may lose some recent data that was unable to be transferred to the disk. Other topics covered include tag queing, a process in which each process request passed to the disk driver is assigned a numeric tag, semantics, and file storage.
