Computer architecture is the field concerned with the conceptual design and operational structure of computer systems: how processors, memory and input and output are organized so programs execute efficiently. Its documented history runs from the correspondence between Charles Babbage and Ada Lovelace describing the analytical engine to John von Neumann's 1945 First Draft of a Report on the EDVAC, the paper whose stored program organization nearly every later machine follows.

John von Neumann's 1945 First Draft of a Report on the EDVAC described the stored-program architecture, with a single memory holding both instructions and data, that gives the von Neumann architecture its name and underlies most computer designs since.
