What was the name of the first computer developed?

The first computer developed was called the Z1, which was created by German engineer Konrad Zuse in 1936. The Z1 was a mechanical computer and is notable for being one of the earliest programmable computers. It utilized binary coding and was capable of performing basic arithmetic operations, making significant advancements in the field of computing at the time.

The Z1 laid the foundation for later computers, including Zuse's subsequent models, which were more advanced. Each of the other choices represents significant developments in computer history, but they came after the Z1. For instance, the ENIAC was the first fully electronic general-purpose computer, completed in 1945, and the UNIVAC was the first commercial computer, introduced in the early 1950s. The Z3, also created by Zuse, followed the Z1 and became the first electromechanical programmable computer in 1941. Therefore, while all the options are important in their contributions to computing, the Z1 is recognized as the first.
