  1. The Story of Computers Chapter 10: The Stored Program Architecture <your name here>

  2. The ENIAC • Mauchly and Eckert develop the ENIAC for the Army at U. Penn • the first electronic programmable digital computer system

  3. The ENIAC • Notable for its size and engineering complexity as well as speed and performance • Composed of 17,000 vacuum tubes and weighing nearly 30 tons!

  4. The ENIAC • Programming required patching wires to circuits, setting switches, and reconfiguring the machine by hand

  5. Von Neumann Visits the Moore School • By the Spring of 1944, it was evident to Mauchly and Eckert that improving programming was a top priority • In the fall, mathematician John von Neumann visits the Moore School to participate in a new project

  6. The EDVAC Called the EDVAC, the new design included the idea storing a symbolic version of the program in some mechanism. Von Neumann publishes a draft of the design which is widely circulated

  7. The Von Neumann Architecture Von Neumann and the IAS Computer The stored program concept permitted the program to be loaded into the computer and executed automatically. This made operating computers easier as well as reusing programs simpler. Later this concept came to be known as the von Neumann architecture.

  8. The EDSAC • The first operational stored program computer was developed in Britain in 1949 at Cambridge by Maurice Wilkes • It featured a total of 1K memory storage
