- Utbildning
Geek Author presents educational series covering computer organization, computer architecture, and embedded system design. Each episode is a concise step taking the listener on a journey from the foundations of digital logic up to computer architecture and finally to system level input and output. The series is presented by engineer, author, and educator David Tarnoff. After a career in industry designing motherboards and BIOSes, David began teaching hardware concepts to students of computer science. Twenty-five years later, he’s taking that content and providing it to anyone with an interest in what makes a computer tick.

An Intro to the Computer Organization Series
This episode provides a brief introduction to the Geek Author series, Computer Organization and Design Fundamentals, and to it's host, David Tarnoff.
-
The Importance of Hardware Design
In this episode, we discuss the importance of hardware design to anyone interested in creating computing solutions.
-
Real World Analog versus the Digital Computer
In this episode, we make the distinction between analog (real-world) values and the values that a computer uses, in other words, digital. We discuss the benefits of digital over analog and describe a simple system to capture analog values.
-
The Anatomy of a Binary Signal
In this episode, we define the components of a single binary signal as its value changes over time. This will provide us with a starting point for the terminology we will be using throughout the rest of the series.
-
Pulse Width Modulation
In this episode, we show how a binary signal can be used to give the appearance of an analog output. We then use this understanding to show how to dim an LED on the Arduino open source platform.

How Computers Count without Fingers
In this episode, we visit some ancient Sumerians so we can expand our view of finger counting and see how this applies to counting with transistors. From this, we will have the basis for unsigned binary integers and the humble binary digit or bit. We also show how to calculate the upper limit to which a fixed number of transistors can count.
