Line 8:

The earliest memory architectures are the [[Harvard architecture]], which has two physically separate memories and data paths for program and data, and the [[Princeton architecture]] which uses a single memory and data path for both program and data storage.<ref name="adafruit" />

Most general purpose computers use a hybrid split-cache [[modified Harvard architecture]] that appears to aan application program to have a pure Princeton architecture machine with gigabytes of [[virtual memory]], but internally (for speed) it operates with an instruction cache physically separate from a data cache, more like the Harvard model.<ref name="adafruit" >
