Chlorine gas can corrode electronic components by forming hydrochloric acid when it comes into contact with moisture in the air. This can lead to damage to the components and result in malfunctions or complete failure of electronic devices. It is important to keep electronic equipment away from chlorine gas to prevent damage.
The first programmable electronic digital computer was called the ENIAC (Electronic Numerical Integrator And Computer). The contract to make it was signed on June 5, 1943, and the only one manufactured was on February 14, 1946. It was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania. For the very earliest computer, see the related link to the Antikythera Mechanism.in 1942, the first electronic digital computer, the ABC was built by John V. Atanasoff and his graduate student Clifford Berry. it was built in Ames, Iowa.in 1943, the first programmable electronic digital computer, the Colossus was built by Tommy Flowers for Bletchley Park. up to VE day 11 of these computers were built.in 1946, ENIAC was finished, as told above.
Their active components were vacuum tubes (which were large) which generated lots of heat (which needed a large cooling system to remove that heat from the computer).

What made modern computers possible was the invention of something that could do calculations and other information processing with no moving parts and do it very fast. That something was electronic components. With electronic components, a fast and efficient machine such as Babbage proposed could be built with all four components essential to modern computing. source: Intel offical wesite
This does not have a straightforward answer. The first digital computer was called the ABC computer developed by Atanasoff and Berry in 1942 but it was never fully functional. ABC stood forr Atanasoff-Berry Computer. A court judge named Atanasoff the inventor of the digital computer. The first working digitale computer was the ENIAC developed by Mauchly and Eckert in 1946. ENIAC stood for Electronic Numerical Integrator And Calculator.
The very first electronic spreadsheet program was called VisiCalc, invented by Dan Bricklin and Bob Frankston. It was launched in 1979 on an Apple computer.
