Sorting and Collating,decided that sorting and numerical computing needed to be unified and implemented in a single high-speed machine. The early history of the mergesort algorithm and the beginnings of a systematic study of sorting procedures for electronic computers are described.

EDVAC and Its Codes,les of the use of the both codes are given and the way that von Neumann laid out the code in the manuscript is explained. The notion of substitution is identified as the unifying concept underlying von Neumann’s design of these codes.

Sorting and Collating, between von Neumann’s code and established data-processing procedures used on punched card machines. Starting in late 1944, John Mauchly interviewed several intensive users of punched cards in a variety of governmental agencies, and his notes allow us to pinpoint the moment at which the EDVAC team

The familar EDVAC of the . is described in relation to the proposals for the Bell Labs Relay Calculator, and the unfamiliar manuscript reproduced in Appendix A allows us to give a detailed description of how the plans
