Question

The Electronic Discrete Variable Automatic Computer (EDVAC) is built by:

• A. Howard A. Aiken
• B. John Von Neumann
• C. John Atanasoff
• D. John Maulchy and J. Presper Eckert

Hint:

Mauchly and Eckert (ENIAC/EDVAC) are the duo responsible for the transition from mechanical to fully electronic general-purpose computing.

Answer 1

The Correct Option is D

Concept: The history of early computing is defined by several key machines. EDVAC was one of the first electronic computers to use the stored-program concept, which is the basis for almost all modern computers.

Step 1: Trace the origins of EDVAC.
EDVAC was the successor to the ENIAC (Electronic Numerical Integrator and Computer). Both of these revolutionary machines were designed and proposed by the same primary team at the University of Pennsylvania.

Step 2: Identify the creators.
The primary designers were John Mauchly and J. Presper Eckert. While John von Neumann was heavily involved and wrote the famous first draft of a report on EDVAC that popularized the "Von Neumann Architecture," the physical building and engineering were led by Mauchly and Eckert.

Step 3: Distinguish from other pioneers.
- Howard Aiken developed the Harvard Mark I. - John Atanasoff built the ABC (Atanasoff-Berry Computer).
