But How Do It Know

This book thoroughly explains how computers work. It starts by fully examining a NAND gate, then goes on to build every piece and part of a small, fully operational computer. The necessity and use of codes is presented in parallel with the apprioriate pieces of hardware. The book can be easily understood by anyone whether they have a technical background or not. It could be used as a textbook.

Om hvordan mikroprocessorer fungerer, med undersøgelse af de nyeste mikroprocessorer fra Intel, IBM og Motorola.

A Daily Show correspondent turns her unique wit on herself, discussing what it was like to be raised by a Wiccan mother, her parents' uncomfortable sex talks, all the strange jobs she had on the road to The Daily Show and much more.

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.

Yes, But How Do You Know? is an invitation to think philosophically through the use of sceptical ideas. Hetherington challenges our complacency and asks us to reconsider what we think we know. How much can we discover about our surroundings? What sort of beings are we? Can we trust our own reasoning? Is science all it is cracked up to be? Can we acquire knowledge of God? Are even the contents of our own minds transparent? In inviting, lucid prose, Hetherington addresses these questions and more, using scepticism to illuminate many perennial philosophical puzzles.

Have you ever asked yourself how the inventions, gadgets, and devices that surround us actually work? Discover the hidden workings of everyday technology with this graphic guide. How Technology Works demystifies the machinery that keeps the modern world going, from simple objects such as zip fasteners and can openers to the latest, most sophisticated devices of the information age, including smartwatches, personal digital assistants, and driverless cars. It includes inventions that have changed the course of history, like the internal combustion engine, as well as technologies that might hold the key to our future survival, including solar cells and new kinds of farming to feed a growing population. Throughout the book, step-by-step explanations are supported by simple and original graphics that take devices apart and show you how they work. The opening chapter explains principles that underpin lots of devices, from basic mechanics to electricity to digital technology. From there, devices are grouped by application--such as the home, transportation, and computing--making them easy to find and placing similar devices side by side. How Technology Works is perfect for anyone who didn't have training in STEM subjects at school or is simply curious about how the modern world works.
