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.

This textbook covers the traditional introductory Computer Science I topics but takes a unique approach. Topics are covered in a language-agnostic manner in the first part with supplemental parts that cover the same concepts in a specific language. The current version covers C, Java, and PHP. This textbook as been used in several Computer Science I sections over multiple years at the University of Nebraska-Lincoln.
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.

The midterm represents the final week of working in Word. You will be asked to complete documents that demonstrate that you understand basic rules and best practices to ensure your online research is reliable as well as demonstrate skill in the proper use of Word features covered during the first 5 weeks of the course.
Skills & Knowledge Attained: *Time management – You were asked to think about your midterm topic in week 1 and declare it in a post in week 2 and given several weeks to prepare and do the necessary research. Research document should demonstrate the time provided was used to spread out the work so that it was not done in a rush and/or at the last minute. *Best practices on how to check a website for accuracy and truth as well as appropriateness as research source. *Proper application of MLA requirements using Microsoft Word Reference features, such as adding footnotes, citations, and generating a bibliography from correctly added citations as well as placement and content of appropriate header and footer. *The paper should be an original piece of writing based on properly cited online research, that demonstrates understanding of the topic researched and should explain in your own words, using proper spelling and grammar, what you have learned about your chosen topic.

The text, labs, and review questions in this book are designed as an introduction to the applied topic of computer security (cybersecurity). With these resources students will learn ways of preventing, identifying, understanding, and recovering from attacks against computer systems. This text also presents the evolution of computer security, the main threats, attacks and mechanisms, applied computer operation and security protocols, main data transmission and storage protection methods, cryptography, network systems availability, recovery, and business continuation procedures.

This core Computer Usage and Applications text provides a survey of computer skills necessary to succeed in professional and academic careers. This includes a survey of Operating Systems, Microsoft Office applications such as Word, Excel, Access and PowerPoint, as well as Google Apps. There is a focus on analyzing and solving business problems in the most efficient way possible. Students are given clear, easy-to-follow instructions for each skill presented and are also provided with opportunities to learn additional skills related to the personal and professional objectives presented. Students will learn the objectives with detailed instruction in the ‘Learn It’ and ‘Practice’ assignments; and expand their knowledge with ‘Master’ and ‘Challenge It’ activities. Students are challenged to use critical thinking to solve real world scenarios. For example, ‘fix-it’ case studies are included so students gain an appreciation for the real world application of these technologies. Computer Usage and Applications is an independent publication and is not affiliated with, nor has it been authorized, sponsored, or otherwise approved by Microsoft Corporation. Our adapted work uses all Microsoft screenshots under fair use. If you plan to redistribute our book, please consider whether your use is also fair use.

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.
