This animation corresponds to the classroom activity / layout. The boy represents instructions and data being transferred from secondary storage to RAM (slow). The frog represents transfer between RAM and CPU (via cache). The bat represents the transfer from cache to CPU (fast). Performance can be increased by having a larger RAM or larger cache. Can you think of other ways?
Next steps would be: The boy reaches out and grabs an instruction (maybe a number) from secondary storage and transfers it to RAM. This is then transferred to cache and then to CPU. Other (next) instructions are grabbed and transferred as this is happening.
