What does ENIAC stand for?

ENIAC stands for Electronic Numeric Integrator and Computer. It was one of the earliest electronic general-purpose computers, developed during World War II. The significance of ENIAC lies in its ability to perform a wide variety of calculations at high speed, which was revolutionary at the time. It was primarily designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory. ENIAC’s architectural design included a large number of vacuum tubes and could process numbers in decimal, making it a numeric integrator, which is reflected in its name.

The other options presented do not accurately describe ENIAC’s purpose or its historical context. While they may sound plausible within a modern computing context, they do not correlate with the original function or the design intentions behind ENIAC. Thus, the correct answer emphasizes the historical and technical significance of the machine in computing history.
