Use your Raspberry Pi to get smart about computing fundamentals In the 1980s, the tech revolution was kickstarted by a flood of relatively inexpensive, highly programmable computers like the Commodore. Now, a second revolution in computing is beginning with the Raspberry Pi. Learning Computer Architecture with the Raspberry Pi is the premier guide to understanding the components of the most exciting tech product available. Thanks to this book, every Raspberry Pi owner can understand how the computer works and how to access all of its hardware and software capabilities. Now, students, hackers, and casual users alike can discover how computers work with Learning Computer Architecture with the Raspberry Pi. This book explains what each and every hardware component does, how they relate to one another, and how they correspond to the components of other computing systems. You'll also learn how programming works and how the operating system relates to the Raspberry Pi's physical components. Co-authored by Eben Upton, one of the creators of the Raspberry Pi, this is a companion volume to the Raspberry Pi User Guide An affordable solution for learning about computer system design considerations and experimenting with low-level programming Understandable descriptions of the functions of memory storage, Ethernet, cameras, processors, and more Gain knowledge of computer design and operation in general by exploring the basic structure of the Raspberry Pi The Raspberry Pi was created to bring forth a new generation of computer scientists, developers, and architects who understand the inner workings of the computers that have become essential to our daily lives. Learning Computer Architecture with the Raspberry Pi is your gateway to the world of computer system design.

Finally, here is a single volume containing all of the engineering information needed to successfully design and implement any type of wireless network!

The worldwide video game console market surpassed $10 billion in 2003. Current sales of new consoles is consolidated around 3 major companies and their proprietary platforms: Nintendo, Sony and Microsoft. In addition, there is an enormous installed "retro gaming" base of Ataria and Sega console enthusiasts. This book, written by a team led by Joe Grand, author of "Hardware Hacking: Have Fun While Voiding Your Warranty", provides hard-core gamers with they keys to the kingdom: specific instructions on how to crack into their console and make it do things it was never designed to do. By definition, video console game players like to have fun. Most of them are addicted to the adrenaline rush associated with "winning", and even more so when the "winning" involves beating the system by discovering the multitude of "cheats" built into most video games. Now, they can have the ultimate adrenaline rush---actually messing around with the soul of the machine and configuring it to behave exactly as the command. This book builds on the motto of "Have Fun While Voiding Your Warranty" and will appeal to the community of hardware geeks who associate unscrewing the back of their video console with para-jumping into the perfect storm.
