Book Description
The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

Book Description
A 2020 LOCUS AWARD FINALIST Jeff VanderMeer's Dead Astronauts presents a City with no name of its own where, in the shadow of the all-powerful Company, lives human and otherwise converge in terrifying and miraculous ways. At stake: the fate of the future, the fate of Earth—all the Earths. A messianic blue fox who slips through warrens of time and space on a mysterious mission. A homeless woman haunted by a demon who finds the key to all things in a strange journal. A giant leviathan of a fish, centuries old, who hides a secret, remembering a past that may not be its own. Three ragtag rebels waging an endless war for the fate of the world against an all-powerful corporation. A raving madman who wanders the desert lost in the past, haunted by his own creation: an invisible monster whose name he has forgotten and whose purpose remains hidden.

Book Description
Computer Hardware Maintenance presents the full scope and understanding of how the PC hardware maintenance function should operate and be managed in an organization, including steps involved in containing costs, keeping records, and planning the integration of the help desk function. In today's IS department too often the PC hardware maintenance function is treated as a 'necessary evil', with the understanding that eventually all equipment will have some degree of mechanical or electrical failure. This book discusses scenarios where keeping the maintenance function internal is most viable and where having it external, from a depot service, pickup and delivery, or on-site service, is most viable. Computer Hardware Maintenance concludes with brief descriptions of available third-party systems and how emerging trends in PC hardware configuration as proposed by the Desktop Management Task Force (DMTF) will have a major impact on the PC hardware maintenance function in the future.

Book Description
Hardware and Computer Organization is a practical introduction to the architecture of modern microprocessors. This book from the bestselling author explains how PCs work and how to make them work for you. It is designed to take students "under the hood" of a PC and provide them with an understanding of the complex machine that has become such a pervasive part of everyday life. It clearly explains how hardware and software cooperatively interact to accomplish real-world tasks. Unlike other textbooks on this topic, Dr. Berger’s book takes the software developer’s point-of-view. Instead of simply demonstrating how to design a computer’s hardware, it provides an understanding of the total machine, highlighting strengths and weaknesses, explaining how to deal with memory and how to write efficient assembly code that interacts directly with, and takes best advantage of the underlying hardware. The book is divided into three major sections: Part 1 covers hardware and computer fundamentals, including logical gates and simple digital design. Elements of hardware development such as instruction set architecture, memory and I/O organization and analog to digital conversion are examined in detail, within the context of modern operating systems. Part 2 discusses the software at the lowest level ̧ assembly language, while Part 3 introduces the reader to modern computer architectures and reflects on future trends in reconfigurable hardware. This book is an ideal reference for ECE/software engineering students as well as embedded systems designers, professional engineers needing to understand the fundamentals of computer hardware, and hobbyists. The renowned author's many years in industry provide an excellent basis for the inclusion of extensive real-world references and insights Several modern processor architectures are covered, with examples taken from each, including Intel, Motorola, MIPS, and ARM

Book Description
New from Delmar Learning, Electronics for Computer Technology is perfect for today's career-minded students as well as anyone with a keen interest in troubleshooting computer devices, components and electrical circuits. The first chapter introduces system-level topics, including representative systems, system notations, functional hierarchies, system connectivity, and system-level troubleshooting. In subsequent chapters, direct references are made to system applications in order to put each topic in the context of an overall system. Some software (programming) topics are addressed, yet emphasis throughout the book is on hardware, including all of the physical parts of the computer plus various electronic components within the computer. Electronic devices are also discussed, along with an overview of digital electronics, computers, and telecommunications. Readers will learn to apply system-level troubleshooting techniques to localize the detailed troubleshooting effort. Benefits: new system-level thinking and troubleshooting skills may be used to open doors to employment or as preparation for advanced study of modern industrial electronics, robotics, or other industrial control systems "System Perspective" features appear at strategic points, illustrating how a device or circuit being discussed is actually used in a practical, functional system such as a computer "Circuit Exploration" exercises are included in every chapter, providing opportunities to gain hands-on troubleshooting experience in a lab setting or circuit simulation environment step-by-step calculator sequences are provided whenever a new type of calculation is introduced, minimizing the learning curve for novices CD includes pre-created MultiSIM circuits and Textbook Edition of MultiSIM the behavior of components is discussed and explained in terms of Ohm's Law, Kirchhoff's Law, and basic circuit principles wherever practical, making this book ideal for beginners numerical circ
