If till now you are vexed about the first digital electronic computer in the world, then ENIAC is the answer. ENIAC is abbreviation from Electronic Numerical Integrator and Computer. ENIAC is first digital electronic computer in the world, it developed by ARMY ORDNANCE to calculate ballistic shoting tables at second World war.

ENIAC developed by John Mauchly and J. Presper Eckert in Moore School of the University of Pennsylvania. ENIAC’s weight is 30 tons, utilizes 200 kWatt electricity and consisted of 18000 air vacuum tubes, 1500 relay, and over 100000 transistors, capacitor and inductor.

ENIAC finalized in 1945 and announced to public in 1946. besides for ballistic, ENIAC also utilized for forecast of weather, calculate the atomic energy, cosmic [light/ray] study, random number study, scheme of wind tunnel and other scientific study.

ENIAC can operate addition in 200 ms, multiplication in 3 ms, and division of in 30 ms. Although still in a real simple form or even primitive because of its size is very big, ENIAC has been registered in world history as the digital electronic computer in the world.
