[disk storage] In disk storage and drum memory, interleaving is a technique used to improve access performance to storage by putting data accessed sequentially into non-sequential sectors. Historically, interleaving was used in ordering block storage on disk-based storage devices such as the floppy disk and the hard disk. The primary purpos...
• (p. pr. & vb. n.) of Interleave
a process of systematically changing the bit sequence of a digital signal, usually as part of the channel coding, in order to reduce the influence of error bursts that may occur during transmission NOTE - In French, the term 'entrelacement' is also used with the meaning of interlace in relation to scanningthe systematic distribution of data words being recorded so that originally consecutive words are separated, thus changing burst errors into evenly distributed errors which are more easily corrected
Introducing alternate sheets of blank paper between the printed sheets as they come off the press to prevent set off.
The placing of a sheet of paper between two adjacent layers of metal to facilitate handling and shearing of rectangular sheets, or to prevent sticking or scratching.
a method for making data retrieval more efficient by rearranging or renumbering the sectors on a hard disk or by splitting a computer's main memory into sections so that the sectors or sections can be read in alternating cycles.
The placing of a sheet of paper between two adjacent layers of metal to facilitate handling and shearing of rectangular sheets, or to prevent sticking or scratching.
