Hertz is a measure of how fast clock changes (higher hertz equals more instructions processed per second. Top of triangle (hierarchy) is what computer can access easily things lower in the triangle take longer to reach acess: registers at the top, ram (random access memory) in the middle, hdd at the bottom.
