Computer Organization and Design Fundamentals Series
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
5.0 stars

For all intents and purposes, this show is the fourth edition of the textbook Computer Organization and Design Fundamentals by David Tarnoff. Since the first edition came out in 2005, the PDFs have been made free for download to anyone interested in computer organization. With the trend toward audio and video instructional material, it was time for an update.

The presentation of the material in this series will be similar to that of the original textbook. In the first third, we will discuss the mathematical foundation and design tools that address the digital nature of computers. This will include an introduction to the differences between the physical world and the digital world, how those differences affect the way the computer represents and manipulates data, and the use and design of digital logic and logic gates. In the second third, the fundamentals of the digital logic and design will be used to design common circuits such as binary adders, describe checksums and cyclic redundancy checks, network addressing, storage devices, and state machines. The final third will examine the top-level view of the computer. This will include a discussion of the memory hierarchy and its components, the components of a CPU, and maybe even a discussion of assembly language along with some examples.

How elastic are rubber bands? There's more than one way to answer this question. The word "elasticity" is commonly used to describe things that have a stretchy quality to them. You might try to answer the question by stretching a rubber band across your finger and shooting it across the room. To an economist, however, elasticity can have a whole other meaning. Learn more in this episode of The Economic Lowdown.

Língua da Gente

0.0 stars

In Brazil, the term língua da gente (literally ‘language of the people’) refers to the way that people actually talk in everyday speech. And that, in essence, is the object behind this series. We hope to provide practical lessons that demonstrate how people really speak, and we do this by presenting brief, slice-of-life dialogs, which focus on some daily situation, scenario, or task that we encounter every day.

Each audio podcast, generally between 8-12 minutes, includes the presentation of a brief dialog, a line-by-line English translation, and more in-depth analysis of the pronunciation, vocabulary, grammar, and cultural content in the lesson. Discussion blogs also accompany each lesson, providing community interaction for comments and questions. In broad terms, the lessons are subdivided into three levels of difficulty: Beginning, Elementary, and Intermediate. Additionally we have a cultural show that covers current events and related social issues.

In a market economy, price signals prevent massive shortages and ensure that consumer wants are largely satisfied. In this podcast, hear how price signals from gas prices influence decision-making for both a father of three and a production supervisor for an oil refinery. Do you see price signals influencing decisions in your life?

Is public transportation a public good? How about national defense? Knowing the characteristics of public goods will help you understand why private firms excel at producing private goods, but they have little incentive to produce public goods. Rather, if society wants public goods, government must produce them. This episode of The Economic Lowdown defines the characteristics of private and public goods and explains why these characteristics help determine who is best positioned to produce each.
