Birth of Computers (1940-1950) **WWII** World War II brought concerns about how to calculate the logistics of such a large scale battle. The United States needed to calculate ballistics, deploy massive amounts of troops, and crack secret codes. The military started a number of research projects to try and build computers that could help with these tasks and more. In 1931 the U.S. Navy and IBM began working together to build a general-purpose computer called the Mark 1. It was the first computer to use the base-2 binary system, was programmable, and made of vacuum tubes, relays, magnets, and gears. The Mark 1 was completed in 1944. [20 The Mark 1 had a memory for 72 numbers and could perform 23-digit multiplication in 4 seconds. It was operational for 15 years and performed many calculations for the U.S. Navy during WWII.
