Stored program computer

made up of:

Von Neumann Architecture

  • three key concepts
    • data and instructions are stored in a single read-write memory
    • contents of memory are addressable by location, without regard to the type of data contained
    • execution occurs in a sequential fashion, unless explicitly altered, from one instuction to the next
  • programs and data are the same thing
    • and so its possible to write soure code (data) and comile them into executables (programs) that can be loaded as data and then executed as programs
