The word "COMPUTER" is not an abbreviation itself, but rather a standalone word derived from the verb "compute." While some informal or contextual shortenings like "comp" might be used, there is no universally recognized or official abbreviation for "COMPUTER" in the same way that there are for terms like "e.g." or "Dr." Attempts to create an acronym for "COMPUTER" (e.g., "Common Operating Machine Purposely Used for Technical and Educational Research") are generally considered backronyms and not the origin or a true abbreviation of the word.
