What was ENIIAC?

Answer 1

ENIAC, which stands for Electronic Numerical Integrator and Computer, was one of the earliest general-purpose electronic digital computers, completed in 1945. It was designed to calculate artillery firing tables for the U.S. Army during World War II and was significant for its use of vacuum tubes, which allowed for much faster calculations than previous mechanical computers. ENIAC could perform thousands of calculations per second, laying the groundwork for future developments in computing technology. It was also notable for its programmability, as it could be reconfigured to solve different types of problems.
