First Draft of a Report on the EDVAC

The First Draft of a Report on the EDVAC is a seminal document in the history of computing, authored by the renowned mathematician John von Neumann in 1945. This 101-page draft laid the foundational framework for what would later be known as the von Neumann architecture, a key concept that has influenced the design of most of the computers we use today.

Background

The EDVAC, or Electronic Discrete Variable Automatic Computer, was one of the earliest electronic computers, conceived as a successor to the ENIAC. The EDVAC project was initiated at the Moore School of Electrical Engineering at the University of Pennsylvania. The project brought together many notable figures in computing, including John Mauchly, J. Presper Eckert, Arthur Burks, and Herman Goldstine.

Content and Impact

The "First Draft" detailed the concept of a stored-program computer, in which both data and instructions are stored in the computer's memory, allowing for greater flexibility and efficiency. This concept was a departure from earlier computing systems which were hardwired to perform specific tasks. The architecture proposed by von Neumann emphasized a central processing unit (CPU), a memory to store both data and instructions, and input/output mechanisms.

This proposal not only influenced the design and development of the EDVAC itself but also inspired other early computers, such as the EDSAC and eventually the UNIVAC I. The document was circulated widely amongst the computing community and served as a critical reference point for computer development in the post-war era.

Contributors and Acknowledgments

While John von Neumann is often credited with the architecture's development, the project was collaborative. The lack of proper acknowledgment of all contributors, particularly Eckert and Mauchly, in the initial draft led to some controversy. Despite this, the draft served as a critical stepping stone in the evolution of modern computing systems.
