The elemental principle of storing systems within the computer's memory together with the data they operate on may be the crux of the von Neumann, or saved plan[citation required], architecture. In some instances, a computer might retailer some or all of its system in memory that is retained independent from the information it operates on. This can be known as the Harvard architecture once the Harvard Mark I computer.
