Code PDF Author: Charles Petzold
Publisher: Microsoft Press
ISBN: 0137909292
Category : Computers
Languages : en
Pages : 563

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.

United States Diplomatic Codes and Ciphers, 1775-1938

United States Diplomatic Codes and Ciphers, 1775-1938 PDF Author: Ralph E. Weber
Publisher: Routledge
ISBN: 1351316184
Category : Business & Economics
Languages : en
Pages : 835

Book Description
United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.
