Today’s lesson was a bit of a race, it covered Cache memory, SRAM & DRAM.
Its important that you remember that Cache Memory is not the same as Internet Cache. If you can’t get your head around how me running back and forth to the filing cabinet was caching then have a look here.
As a by the way, we also learned today that a memory location can hold more that one bit. I wonder if that will be useful in the future?
