Book Description
Most introductory books about computers are long, detailed technical books such as those used in a computer science course or else tutorials that provide instructions on how to operate a computer with little description of what happens inside the machine. This book fits in the large gap between these two extremes. It is for people who would like to understand how computers work, without having to learn a lot of technical details. Only the most important things about computers are covered. There is no math except some simple arithmetic. The only prerequisite is knowing how to use a web browser. As an alternative or adjunct to reading the book, you can watch a series of short videos by going to youtube.com and searching for “Understanding Computers, Smartphones and the Internet”. Only current day technology is covered. People who are interested in learning about how computers evolved from the earliest machines can read the companion book “A Concise History of Computers, Smartphones and the Internet”. While originally intended for people who are not in the computer field, this book is also useful for those taking a coding course or an introductory computer science course. Even people already in the computer field will find things of interest in this book.

Book Description
The very first electronic computers were invented at the end of World War II. They were very large machines that could only be used in special air conditioned rooms. Today, almost everybody carries a computer in their pocket, in their mobile phone. How did all this come about in only 70 years? This book is for people who would like to know the answer to this question. It tells this exciting story, with a lot of pictures. This book is not a complete history, rather it is a concise history that covers the most important people, companies and inventions that led to where we are today. The first chapter covers the evolution of computer hardware - the physical machine. The second chapter focuses on the software - the programs that provide the instructions that tell the hardware what to do. The third chapter covers the most important data networks that were developed so that computers could communicate with each other, ending with the Internet which only became the dominant computer network after 1995. The last chapter on Smartphones traces its history from the discovery of radio waves in the late 19th century to the Apple iPhone. This book does not require a lot of technical knowledge about computers. People who are interested in learning more about how computers actually work can read the companion book “Understanding Computers, Smartphones and the Internet”, by Ernie Dainow.

Book Description
Surviving in the Hi-Tech World follows the many ups and downs of my years as a software developer in the high-tech industry, starting in the mainframe era. It provides a window into what it is like to work in the computer field. I worked for many different organizations, from academia and large companies to medium sized companies and several startups. The stories weave my work experience with explanations of the technology of the period. In the process it follows the revolutionary changes in computer hardware and software from large mainframes to personal microcomputers and the evolution of early networks into the global Internet. When I was a psychology student in university, I became interested in the possibilities of using computers to model and understand human thinking. I completed a Master's degree in Artificial Intelligence in Computer Science in 1970, but my interest in doing academic research shifted to an interest in building real world systems. My first job in computers was with Univac, the company that had built one of the first general purpose commercial computers. I switched jobs for many different reasons – sometimes because of interest and at other times because of necessity. Each chapter in the book covers the different jobs and places that I worked. My journey took me from Montreal to London, Glasgow, Wisconsin, Vancouver and Toronto. Each job has its own story as I progressed through a series of adventures. There are stories of people who became multi-millionaires and one who went to jail.

Book Description
An approachable, hands-on guide to understanding how computers work, from low-level circuits to high-level code. How Computers Really Work is a hands-on guide to the computing ecosystem: everything from circuits to memory and clock signals, machine code, programming languages, operating systems, and the internet. But you won't just read about these concepts, you'll test your knowledge with exercises, and practice what you learn with 41 optional hands-on projects. Build digital circuits, craft a guessing game, convert decimal numbers to binary, examine virtual memory usage, run your own web server, and more. Explore concepts like how to: Think like a software engineer as you use data to describe a real world concept Use Ohm's and Kirchhoff's laws to analyze an electrical circuit Think like a computer as you practice binary addition and execute a program in your mind, step-by-step The book's projects will have you translate your learning into action, as you: Learn how to use a multimeter to measure resistance, current, and voltage Build a half adder to see how logical operations in hardware can be combined to perform useful functions Write a program in assembly language, then examine the resulting machine code Learn to use a debugger, disassemble code, and hack a program to change its behavior without changing the source code Use a port scanner to see which internet ports your computer has open Run your own server and get a solid crash course on how the web works And since a picture is worth a thousand bytes, chapters are filled with detailed diagrams and illustrations to help clarify technical complexities. Requirements: The projects require a variety of hardware - electronics projects need a breadboard, power supply, and various circuit components; software projects are performed on a Raspberry Pi. Appendix B contains a complete list. Even if you skip the projects, the book's major concepts are clearly presented in the main text.

Book Description
Computers are the most complex machines that have ever been created. This book will tell you how they work, and no technical knowledge is required. It explains in great detail the operation of a simple but functional computer. Although transistors are mentioned, relays are used in the example circuitry for simplicity. Did you ever wonder what a bit, a pixel, a latch, a word (of memory), a data bus, an address bus, a memory, a register, a processor, a timing diagram, a clock (of a processor), an instruction, or machine code is? Unlike most explanations of how computers work which are a lot of analogies or require a background in electrical engineering, this book will tell you precisely what each of them is and how each of them works without requiring any previous knowledge of computers, programming, or electronics. This book starts out very simple and gets more complex as it goes along, but everything is explained. The processor and memory are mainly covered.

Book Description
This book examines how today's technology, as it includes smartphones, computers, and the internet, shapes our physical health, cognitive and psychological development, and interactions with one another and the world around us. Technology has become a ubiquitous part of modern life, but its impact on our physical, psychological, and social health and development runs just as deep as does our dependence upon it. How is the development of babies' brains affected by their playing with their parents' smartphones and tablets? How have computers altered the way we process and learn information? How have texting and social networking sites such as Facebook changed the way in which we interact with others? Can online dating lead to meaningful real-world relationships? From Smartphones to Social Media investigates these questions and many complex issues related to technology. Readers will discover what researchers know about how the use of technology affects us through accessibly written, thematic chapters. The main text is complemented by a collection of case studies and interviews with a variety of experts, providing insight into how technology's positive and negative effects manifest in our everyday lives and what we can do to mediate the negative ones.

Book Description
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.
