Suppose you want to build a computer network, one that has the potential to grow to global proportions and to support applications as diverse as teleconferencing, video on demand, electronic commerce, distributed computing, and digital libraries. What available technologies would serve as the underlying building blocks, and what kind of software architecture would you design to integrate these building blocks into an effective communication service? Answering this question is the overriding goal of this book—to describe the available building materials and then to show how they can be used to construct a network from the ground up.

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.

Effective and relevant computer science education is essential to achieving our vision …
Effective and relevant computer science education is essential to achieving our vision that “every student is ready for college, career, and life.” While attention to computer science education has increased in recent years, a lack of awareness about its content and potential impact is widespread. The Washington State Computer Science K–12 Learning Standards are designed to enhance teacher understanding and improve student learning so that students are better equipped for college, career, and life.
Washington is committed to implementing high-quality computer science instruction to:
* Increase the opportunity for all students to gain knowledge of computer science. * Introduce the fundamental concepts and applications of computer science to all students, beginning at the elementary school level. * Make computer science at the secondary level accessible, worthy of a computer science credit, and/or equivalent to math and science courses as a required graduation credit (see Level 3B of computer science standards). * Offer additional secondary-level computer science instruction that allows interested students to study facets of computer science in depth and prepare them for entry into a career or college.
Learning standards describe what students need to know and be able to do. Standards are worded broadly to allow flexibility at the district, building, and classroom levels.

This webinar (recorded Sept. 27, 2017) introduces how to connect other services as add-ons to projects on the Open Science Framework (OSF; https://osf.io). Connecting services to your OSF projects via add-ons enables you to pull together the different parts of your research efforts without having to switch away from tools and workflows you wish to continue using. The OSF is a free, open source web application built to help researchers manage their workflows. The OSF is part collaboration tool, part version control software, and part data archive. The OSF connects to popular tools researchers already use, like Dropbox, Box, Github and Mendeley, to streamline workflows and increase efficiency.

Bluetooth is everywhere—from smartphones to computers to cars. Even though students are exposed to this technology, many are not aware of how they can use it themselves to wirelessly control their own creative projects! For this challenge, students build on what they learned during a previous Arduino maker challenge, Make and Control a Servo Arm with Your Computer, and learn how to control a servo with an Android phone (iPhones do not work with the components used in this challenge). By the end of the exercise, expect students to be wirelessly controlling a servo with a simple phone application!

Students put their STEAM knowledge and skills to the test by creating indoor light fixture “clouds” that mimic current weather conditions or provide other colorful lighting schemes they program and control with smartphones. Groups fabricate the clouds from paper lanterns and pillow stuffing, adding LEDs to enable the simulation of different lighting conditions. They code the controls and connect the clouds to smart devices and the Internet cloud to bring their floating clouds to life as they change color based on the weather outside.

Students are introduced to servos and the flex sensor as they create simple, one-jointed, finger robots controlled by Arduino. Servos are motors with feedback and are extensively used in industrial and consumer applications—from large industrial car-manufacturing robots that use servos to hold heavy metal and precisely weld components together, to prosthetic hands that rely on servos to provide fine motor control. Students use Arduino microcontrollers and flex sensors to read finger flexes, which they process to send angle information to the servos. Students create working circuits; use the constrain, map and smoothing commands; learn what is meant by library and abstraction in a coding context; and may even combine team finger designs to create a complete prosthetic hand of bendable fingers.
