A worm is an elongated, fat, soft-bodied invertebrate (an animal that lacks a backbone). Some species of worms are so different from- even unrelated to- each other that they have not been classified under a single group.

Write Once, Read Many (alternatively Write One, Read Multiple or Write Once, Read Mostly or WORM) refers to a kind of computer storage media that can be written to once, but read from multiple times.There are two types of WORM storage media: those that physically can be written only once (examples of such storage media are CD-R and DVD-R, or electronic circuits such as PROMs) and media that enables WORM capability by using electronic keys or other measures to prevent rewriting. The reasoning behind this artificial hampering of technical capability in the latter case can be found in regulatory authorities requiring certain data archival standards where information has to be reliably kept and made available over a long period of time (an example would be the Securities Exchange Commission).
