In computing, ablock is a sequence of bytes or bits, having a nominal length. Data thusstructured are said to be blocked. The process of putting data intoblocks is called blocking. Blocking is used to facilitate the handlingof the data-stream by the computer program receiving the data. Blockeddata are normally read a whole block at a time. Blocking is almostuniversally employed when storing data to 9-track magnetic tape, torotating media such as floppy disks, hard disks, optical discs and toNAND flash memory. Most file systems are based on a block device, whichis a level of abstraction for the hardware responsible for storing andretrieving specified blocks of data, though the block size in filesystems may be a multiple of the physical block size. In classical filesystems, a single block may only contain a part of a single file. Thisleads to space inefficiency due to internal fragmentation, since filelengths are often not multiples of block size, and thus the last blockof files will remain partially empty. This will create slack spacewhich averages half a block per file.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 140 pp. Englisch.
