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.

Answer: (D) Charles Babbage
Answer: (D) Charles Babbage
Answer: (D) Charles Babbage
Charles Babbage was an English mathematician, philosopher, inventor, and mechanical engineer who designed the Difference Engine and, more importantly, the Analytical Engine. The Analytical Engine is considered the conceptual forerunner of the modern digital computer, incorporating features like an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory, which are fundamental to today's computers. Although it was never fully built in his lifetime, his detailed designs and theoretical work laid the foundational principles for future computer development.
