ENIAC: First Electronic Computer by Mauchly & Eckert

The question asks for the first computer created by JW Mauchly and J Presper Eckert that had minimal mechanical parts, implying an electronic focus.

• J.W. Mauchly and J. Presper Eckert are credited with designing and building the ENIAC (Electronic Numerical Integrator and Computer).
• ENIAC, completed in 1945, is widely regarded as the first large-scale, general-purpose electronic digital computer.
• Unlike earlier machines such as the Harvard Mark I, which relied heavily on mechanical components (electromechanical relays), ENIAC primarily used vacuum tubes for its digital computations, significantly reducing the reliance on mechanical parts and increasing speed.
• Therefore, ENIAC fits the description of the first computer by these creators with minimal mechanical parts, prioritizing electronic operation.
