Final answer:
WWII led to the development of computers through codebreaking efforts like those by Alan Turing, which produced early computational devices, and through the creation of ENIAC to calculate artillery trajectories, accelerating advances in electronics and computation.
Step-by-step explanation:
World War II stimulated the development of modern computers in a couple of significant ways.
Firstly, the Allied efforts to break the Nazi's Enigma code led to the creation of early computing devices, including electromechanical machines such as the one developed by Alan Turing and his team.
This achievement not only assisted in breaking the Enigma code but also laid the groundwork for future advances in computing technology.
Secondly, the Electronic Numerical Integrator and Computer (ENIAC), which was first developed to calculate artillery trajectories for the U.S Army, performed calculations at an electronic speed, marking a substantial progression from mechanical computations.
These innovations fostered the onset of the computer revolution that would begin after the war, leading to a transformation in both military and civilian technology sectors.
