Backup/Restore - permalink - collapse

All > Technology > Storage

A two step process. Information is first copied to non-volatile disk or tape media. In the event of computer problems (such as disk drive failures, power outages, or virus infection) resulting in data loss or damage to the original data, the copy is subsequently retrieved and restored to a functional system.

Binary numbers are used by computers because they can easily be represented and stored by device hardware that utilizes switches, magnetic fields, or charge polarities that are normally in one of two states. The on or off, north or south, or positive or negative states can easily represent the 1s and 0s of a binary number, respectively.

Bit - permalink - collapse

All > Technology > Storage

A single numeric character. Each bit of a binary number can either be 0 or 1. An n-bit number is composed of exactly n numeric characters. An n-bit binary number can have 2n distinct values. For example, an 8-bit binary number has 28 = 256 distinct values, namely all the numbers between 00000000 (0 in decimal) and 11111111 (255 in decimal), inclusive. 8-bit quantization would discretely sample a signal and assign each sampling a value between 0 and 255, permitting 256 possible values.

blocking - permalink - collapse

All > Technology > Storage

The sticking together or adhesion of successive windings in a tape pack. Blocking can result from (1) deterioration of the binder, (2) storage of tape reels at high temperatures, and/or (3) excessive tape pack stresses.

Cinching: The wrinkling, or folding over, of tape on itself in a loose tape pack. Normally occurs when a loose tape pack is stopped suddenly, causing outer tape layers to slip past inner layers, which in turn causes a buckling of tape in the region of slip. Results in large dropouts or high error rates.
