Write-Once Read-Many WORM (WORM) Any type of storage medium to which data can be written to only a single time, but can be read from any number of times. Typically this is an optical disk whose surface is permanently etched using a laser in order to record information. WORM media have a significantly longer shelf life than magnetic media and thus are used when data must be preserved for a long time. (1996-04-01)
Easton's 1897 Bible Dictionary:

Worm (1.) Heb. sas (Isa. 51:8), denotes the caterpillar of the clothes-moth. (2.) The manna bred worms (tola'im), but on the Sabbath there was not any worm (rimmah) therein (Ex. 16:20, 24). Here these words refer to caterpillars or larvae, which feed on corrupting matter. These two Hebrew words appear to be interchangeable (Job 25:6; Isa. 14:11). Tola'im in some places denotes the caterpillar (Deut. 28:39; Jonah 4:7), and rimmah, the larvae, as bred from putridity (Job 17:14; 21:26; 24:20). In Micah 7:17, where it is said, "They shall move out of their holes like worms," perhaps serpents or "creeping things," or as in the Revised Version, "crawling things," are meant. The word is used figuratively in Job 25:6; Ps. 22:6; Isa. 41:14; Mark 9:44, 46, 48; Isa. 66:24.
