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.

This book is designed specifically as a guide for Computer Scientists needing an introduction to Cell Biology. The text explores three different facets of biology: biological systems, experimental methods, and language and nomenclature. The author discusses what biologists are trying to determine from their experiments, how various experimental procedures are used and how they relate to accepted concepts in computer science, and the vocabulary necessary to read and understand current literature in biology. The book is an invaluable reference tool and an excellent starting point for a more comprehensive examination of cell biology.
What impels human beings to harm others -- family members or strangers? And how can these impulses and actions be prevented or controlled? Heightened public awareness of, and concern about, what is widely perceived as a recent explosion of violence -- on a spectrum from domestic abuse to street crime -- has motivated behavioral and social scientists to cast new light on old questions. Many hypotheses have been offered. This volume sorts, structures, and evaluates them.The author draws on contemporary research and theory in varied fields--sociology, clinical psychology, psychiatry, social work, neuropsychology, behavioral genetics, child development, and education--to present a uniquely balanced, integrated, and readable summary of what we currently know about the causes and effects of violence. Throughout, she emphasizes the necessity of distinguishing among different types of violent behavior and of realizing that nature and nurture interact in human development. Controversial issues such as physical punishment and violent television programming receive special attention making this volume an important resource for all those concerned with violent offenders and their victims -- and for their students and trainees.In this third edition of Understanding Violence, author Elizabeth Kandel Englander draws on contemporary research and theory in varied fields to present a uniquely balanced, integrated, and readable summary of what we currently know about the causes and effects of violence, particularly its effect on children. The goal of this textbook is to give a critical review of the most relevant and important areas of research on street and family violence, examining why it is that people become violent. Between 1994 and 2004 the United States benefited from a dramatic decline in rates of violent crime. However, as the economy has weakened in recent years and tougher times have returned, the crime rate has shown signs of a modest
