Why do systems contain several data stores of different size and speed?
What will be an ideal response?
The faster a type of memory is, the more expensive it is. It would nice to be able to fill all of system’s memory needs with the fastest type of memory (registers), but this would be much too expensive (and impractical). It would also be nice to include a lot of memory in the system cheaply, but using only the slowest type of memory (tertiary storage) would make a system much too slow.Therefore, systems include many different types of memory so that the data accessed most-often is stored in the faster type of memory, increasing performance while still being able to store large quantities of data (using the slower types of memory). Also, faster memory is volatile, so a system must include some type of permanent storage so that all data is not lost.
