A brand-new edition of the popular introductory textbook that explores how computer hardware, software, and networks work Computers are everywhere. Some are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak personal data about us. Governments and companies increasingly use computers to monitor what we do. Social networks and advertisers know more about us than we should be comfortable with. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? In this updated edition of Understanding the Digital World, Brian Kernighan explains how computer hardware, software, and networks work. Topics include how computers are built and how they compute; what programming is; how the Internet and web operate; and how all of these affect security, privacy, property, and other important social, political, and economic issues. Kernighan touches on fundamental ideas from computer science and some of the inherent limitations of computers, and new sections in the book explore Python programming, big data, machine learning, and much more. Numerous color illustrations, notes on sources for further exploration, and a glossary explaining technical terms and buzzwords are included. Understanding the Digital World is a must-read for readers of all backgrounds who want to know more about computers and communications.

The basics of how computer hardware, software, and systems work, and the risks they create for our privacy and security Computers are everywhere. Some of them are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak vast amounts of personal data about us. Through computers, governments and companies increasingly monitor what we do. Social networks and advertisers know far more about us than we should be comfortable with, using information we freely give them. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? Understanding the Digital World explains how computer hardware, software, networks, and systems work. Topics include how computers are built and how they compute; what programming is and why it is difficult; how the Internet and the web operate; and how all of these affect our security, privacy, property, and other important social, political, and economic issues. This book also touches on fundamental ideas from computer science and some of the inherent limitations of computers. It includes numerous color illustrations, notes on sources for further exploration, and a glossary to explain technical terms and buzzwords. Understanding the Digital World is a must-read for all who want to know more about computers and communications. It explains, precisely and carefully, not only how they operate but also how they influence our daily lives, in terms anyone can understand, no matter what their experience and knowledge of technology.

The practices of world politics are now scrutinised in a way that is unprecedented, with even those previously – or conventionally assumed to be – disengaged from international affairs being drawn into world politics by social media. Interactive websites allow users to follow election results in real-time from the other side of the world, and online mapping means that the world ‘out there’ is now available on your mobile phone. Understanding Popular Culture and World Politics in the Digital Age engages these themes in contemporary world politics, to better understand how digital communication through new media technologies changes our encounters with the world. Whether the focus is digital media, social networking or user-generated content, these sites of political activity and the artefacts they produce have much to tell us about how we engage world politics in the contemporary age. This volume represents the starting point of a dialogue about how digital technologies are beginning to impact the research and practice of scholars and practitioners in the field of International Relations, with the collection of cutting-edge essays dealing specifically with the intertextuality of world politics and digital popular culture. This book will be of use to International Relations research academics (and critically engaged publics) interested in the core themes of global politics – subjectivity, militarism, humanitarianism, civil society organisation, and governance. The book also employs theories and techniques closely associated with other social science disciplines, including political theory, sociology, cultural studies and media studies.

Digital collaboration is abundant in today’s world, but it is often problematic and does not provide an apt solution to the human need for comprehensive communication. Humans require more personal interactions beyond what can be achieved online. Returning to Interpersonal Dialogue and Understanding Human Communication in the Digital Age is a collection of innovative studies on the methods and applications of comparing online human interactions to face-to-face interactions. While highlighting topics including digital collaboration, social media, and privacy, this book is a vital reference source for public administrators, educators, businesses, academicians, and researchers seeking current research on the importance of non-digital communication between people.

This Open Access book summarizes the key findings from the second cycle of IEA’s International Computer and Information Literacy Study (ICILS), conducted in 2018. ICILS seeks to establish how well schools around the globe are responding to the need to provide young people with the necessary digital participatory competencies. Effective use of information and communication technologies (ICT) is an imperative for successful participation in an increasingly digital world. ICILS 2018 explores international differences in students’ computer and information literacy (CIL), namely their ability to use computers to investigate, create, and communicate at home, at school, in the workplace, and in the community. Participating countries also had an option to administer an assessment of students’ computational thinking (CT), focused on their ability to recognize aspects of real-world problems appropriate for computational formulation, and to evaluate and develop algorithmic solutions to those problems, so that the solutions could be operationalized with a computer. The data collected by ICILS 2018 show how digital competencies can be assessed using instruments representing authentic contexts for ICT use, and how students’ CIL and CT skills relate to school learning experiences, out-of-school contexts, and student characteristics. Those data also show how learning technologies are used in classrooms around the world. Background questionnaires asked students about their use of ICT, and collected information from teachers, schools, and national education systems about the resourcing and teaching of CIL (and CT) within their countries. The results of ICILS 2018 will enable policymakers and education systems to develop a better understanding of the contexts and outcomes of CIL (and CT) education programs.

In Nursing in an Integrated Digital World that Supports People, Systems, and the Planet, the leading-edge innovators in digital health applications, global thought leaders, and multinational, cooperative research initiatives are woven together against the backdrop of health equity and policy-setting bodies, such as the United Nations and the World Health Organization. As the authors prepared this book, the world is struggling with the core issues of access to care, access to needed medical equipment and supplies, and access to vaccines. This access theme is reflected throughout the policy and world health chapters with an emphasis on how this COVID-19 pandemic is exposing the fissures, divides, unfairness, and unpreparedness that are in play across our globe. Sustainability and global health policy are linked to the new digital technologies in the chapters that illustrate healthcare delivery modalities that nurse innovators are developing, leading, and using to deliver care to hard-to-reach populations for better population health. A trio of chapters focus on the underlying need for standards to underlie nursing care in order to capture the data needed to enable new science and knowledge discoveries. The authors give particular attention to the cautions, potential for harm, and biases that the artificial intelligence technologies of algorithms and machine learning pose in healthcare. Additionally, they have tapped legal experts to review the legal statues, government regulations, and civil rights law in place for patients’ rights, privacy, and confidentiality, and consents for the United States, the United Kingdom, and the European Union. The book closes with a chapter written by the editors that envisions the near future—the impact that the new digital technologies will have on how care is delivered, expanding care settings into community and home, virtual monitoring, and patient generated data, as well as the numerous ways that nurses’ roles and technology skill sets must increase to support the global goals of equal access to healthcare. Nursing and Informatics for the 21st Century – Embracing a Digital World, 3rd Edition is comprised of four books which can be purchased individually: Book 1: Realizing Digital Health – Bold Challenges and Opportunities for Nursing Book 2: Nursing Education and Digital Health Strategies Book 3: Innovation, Technology, and Applied Informatics for Nurses Book 4: Nursing in an Integrated Digital World that Supports People, Systems, and the Planet

An in-depth examination of the concept of value in a digital world, an analysis of a range of digital business models and a framework for assessing the value of digital businesses. Assessing the value of traditional business was easy. There are hard, well tested metrics and tangible, measurable assets you can literally kick the tyres of. But how do you measure the value of something that consists of little more than bits of information, brand awareness and a compelling idea? In the winner takes all digital world how do you know if this idea is one that will attract billions of dedicated users or a few thousand fleeting trialists? And, most importantly, how do you assess whether any given business model is robust enough to make billions or flawed in a way that will lose millions? Lopez Lubian and Esteves look at what economic value means in a digital world, and argue for a shift from traditional value metrics to digital value metrics. Through high profile case studies they examine the process of valuation in the digital world – examining the challenges of making objective judgments from subjective information and how to assess the value of data. Next they analyse in depth a number of different digital business models from the perspective of delivering value to investors, stakeholders and society at large. Finally they present a framework model for assessing value in digital business.
