Hi there,

I am trying to have a better understanding of how memory technologies, such as CPU registers & CPU caches, hard disk drives, RAM etc, affect the performance of OS.

How can an operating system use a combination of these memory technologies, with their varying speeds, capacities and costs to achieve overall good performance at acceptable cost?

Would appreciate if anyone can provide me with some insights

These things you want to know are absolutely obvious.

This should help you to understand how does the memory and CPU work together
