What is the full form of ENIAC

ENIAC: Electronic Numerical Integrator and Computer

ENIAC stands for Electronic Numerical Integrator and Computer. It is believed to be the world's first operational electronic digital computer developed in the United States by Army Ordnance to calculate ballistic firing tables to help US troops during World War II. These firing tables enabled the army to predict the target where a shell would hit. It allowed troops to hit their targets more precisely or dodge incoming shells.

It was the world's first general-purpose electronic computer, which was designed to be a modular computer made of separate panels that perform separate functions and run only on electronic components without having any mechanical part to slow it down.

ENIAC's weight was around 30 tons and was spread over an area of 1800 square feet. The main components of the ENIAC include:

• 18,000 vacuum tubes
• 15,00 relays
• Resistors
• Capacitors
• Inductors

Furthermore, it had 20 single-number accumulators as primary functional units along with special units for division, multiplication, and square roots. So, it was not only used by the army but was also suitable for weather prediction, atomic-energy calculations, thermal ignition, cosmic-ray studies, wind-tunnel design, etc. Later, it became obsolete when there was a need for faster computing speeds over time.
