Chapter 9 - Question #1 of 7

What is your definition of a "well-performing" memory, and how does the creation of the memory hierarchy of fig.9-1 help to create good performance?

Well performing memory is memory that can access and move data around quickly.  If speed were the only factor in memory then ideally a computer would use only L1 cache.  Since price ultimately plays a role, well performing memory, using the memory hierarchy is necessary to balance the need for speed and the need to keep costs reasonable to the consumer.
