A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or man made natural fibre like Viscose, Modal & Excel is measured in terms of linear mass density, the weight of a given length of fiber.
The vernam cipher, sometimes known as the 'one time pad', is a stream cipher, which providing certain requirements are met, can be theoretically unbreakable.
PALASM is an early hardware description language, used to translate Boolean functions and state transition tables into a fuse map for use with Programmable Array Logic (PAL) devices introduced by Monolithic Memories, Inc. The language was developed by John Birkner in the early 1980s. It is not case-sensitive. The PALASM compiler was written by MMI in FORTRAN IV on an IBM 370/168. MMI made the source code available to users at no cost.
