Almost everyone these days has a computer. Some may just send and receive email, or browse the World Wide Web. Others write letters or do their home accounts on it. Most people have a basic understanding of how to use a computer, but have no idea how it does the things it does. Some of those people would like to know more, but learning about the insides of a computer, and especially how it works, seems too daunting to try. This book is aimed at anyone in that latter category: anyone who uses a computer, perhaps has never seen inside it, and has no idea how a machine could possibly do all the things it does. But yes, one who is prepared to invest some time and effort in developing understanding of the technology.

Konrad Zuse is one of the great pioneers of the computer age. He created thefirst fully automated, program controlled, freely programmable computer using binary floating-point calculation. It was operational in 1941. He built his first machines in Berlin during the Second World War, with bombs falling all around, and after the war he built up a company that was taken over by Siemens in 1967. Zuse was an inventor in the traditional style, full of phantastic ideas, but also gifted with a powerful analytical mind. Single-handedly, he developed one of the first programming languages, the Plan Calculus, including features copied only decades later in other languages. He wrote numerousbooks and articles and won many honors and awards. This is his autobiography, written in an engagingly lively and pleasant style, full of anecdotes, reminiscences, and philosophical asides. It traces his life from his childhood in East Prussia, through tense wartime experiences and hard times building up his business after the war, to a ripe old age andwell-earned celebrity.

THE TIME HAS COME...for a new era of exploration. With the Dominion War behind them, the crew of the U.S.S. Defiant journeys through the wormhole as Commander Elias Vaughn leads a "corps of discovery" to blaze new trails into the unexplored reaches of the Gamma Quadrant. THE TIME HAS COME ...for a civilization to reach a crossroads. As political forces throughout the Alpha Quadrant intersect at Deep Space 9™ to determine the future of Bajor, the planet's theological unity threatens to shatter. And for Colonel Kira Nerys, the path of the Prophets may become a road to ruin. THE TIME HAS COME...for a father and daughter to confront their past while a mother and son fight for the future, for lovers to be tested and for friendships to transform, and for worlds on opposite ends of the galaxy to face the dusk...or the dawn. TWILIGHT

Not only does almost everyone in the civilized world use a personal computer, smartphone, and/or tablet on a daily basis to communicate with others and access information, but virtually every other modern appliance, vehicle, or other device has one or more computers embedded inside it. One cannot purchase a current-model automobile, for example, without several computers on board to do everything from monitoring exhaust emissions, to operating the anti-lock brakes, to telling the transmission when to shift, and so on. Appliances such as clothes washers and dryers, microwave ovens, refrigerators, etc. are almost all digitally controlled. Gaming consoles like Xbox, PlayStation, and Wii are powerful computer systems with enhanced capabilities for user interaction. Computers are everywhere, even when we don’t see them as such, and it is more important than ever for students who will soon enter the workforce to understand how they work. This book is completely updated and revised for a one-semester upper level undergraduate course in Computer Architecture, and suitable for use in an undergraduate CS, EE, or CE curriculum at the junior or senior level. Students should have had a course(s) covering introductory topics in digital logic and computer organization. While this is not a text for a programming course, the reader should be familiar with computer programming concepts in at least one language such as C, C++, or Java. Previous courses in operating systems, assembly language, and/or systems programming would be helpful, but are not essential.

This is not a book about the history of computing or the history of information. Instead, it is a meta-historical book about the research and writing of these types of history. The formal presentation of historical research in the form of a publication often hides the process by which the topic was selected, boundaries were drawn, evidence was selected, analytic approach was chosen and applied, results were presented, how this work fits into a larger body of scholarship, the implicit goals and biases of the author, and many other similar issues. This process of learning about the various ways to carry out computer history or information history can be enriched by this collection of reflective essays by experienced scholars, discussing the craft that they practice. This is a book that concerns both computer history and information history. The first scholarship in computer history by professionally trained scholars began to appear in the 1970s, so we are approaching a half century of research and publication in this area. The field has generated numerous pieces of exemplary scholarship from various perspectives such as intellectual history of individual technologies, business histories of firms, economic histories of market sectors, externalist histories of funding and professionalization, and so on. However, the field continues to evolve, especially as computing and communication technologies have drawn together in the form of the Internet and social media; and with them a new set of scholars is participating, drawn not only from the history of science and technology, but also from the communication and media studies fields. Powerful theories, approaches, and frameworks are being increasingly drawn more widely from both the humanities and the social sciences to inform the practice of computer history. The scholars in this volume look at what’s happened, what’s happening now, and where historical scholarship in these disciplines is headed.
