Source-derived summary

The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, written by John von Neumann in 1945, describing designs by John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering. The document describes a design architecture for an electronic digital computer made of "organs" that were later understood to have these components:A central arithmetic unit to perform arithmetic operations;

A central control unit to sequence operations performed by the machine;

Memory that stores data and instructions;

An "outside recording medium" to store input to and output from the machine;

Input and output mechanisms to transfer data between the memory and the outside recording medium.

Editorial summary

“Von Neumann architecture” enters the record as computer architecture where code and data share a common bus. Crown Archives preserves that source wording while asking what Neumann, architecture and Computer can confirm, complicate or overturn.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current lead gives the account dated anchors—1945—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Neumann, architecture and Computer.
Editorial analysis

Why this record matters

“Von Neumann architecture” is worth following because a concise public description often conceals a longer documentary argument. Here, Neumann, architecture and Computer provides the most credible route into that argument.

Evidence profile

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 23, 2026. The first chronological checks are 1945.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.

Three-step research path

  1. Establish the record: confirm the title “Von Neumann architecture”, its source revision and the description used here.
  2. Expand the search: follow Von Neumann architecture primary sources, Von Neumann architecture archive and Neumann research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.

Questions for further research
