Clock Speed, Caches & Buses

In this lesson, we examine how computers actually perform transaction and remember information with a discussion on 3 important characteristics of the computing environment, clock speed, caches, and buses.

Clock Speed is  the number of instructions the CPU can execute at a fixed rate, they are measured in Megahertz, MHz, they equal 1 million cycles per second or Gigahertz, GHz which is 1 billion cycles per second, but this is NOT an exact measure of every CPU clock speed, so you’ll learn when, how and why that varies.

Then we discuss Cache, which is stored memory on the CPU.  You’ll learn the caching process which is how the memory is stored relative to the CPUs ability to recall it and what triggers, events, other processes influence that turnaround speed and time by diagramming the entire Cache-CPU layout and transaction.

Upon completion, you’ll be able to diagram this interrelationship between the CPU and its cache process and define the differences between L1, 2, and 3 caches.

Lastly, we discuss the front-side “BUS” and explain what its function is and then demonstrate how it works, and we’ll contrast how the BUS works for Intel chipsets vs. AMD Hyper Transport Bus, and where that memory controller is located.
