Persistence

So far, we have learned how to write programs and communicate our intentions to the Central Processing Unit using conditional execution, funtions, and iterations. We have learned how to create and use data structures in the Main Memory. The CPU and memory are where our software works and runs. It is where all of the "thinking" happens.

But if you recall from hardware architecture discussions, once the power is turned off, anything stored in either the CPU or main memory is erased.
