Comer, one of the architects of the Internet in the late 1970s, explains in clear, non-technical terms what the Internet is, how it works, how it came to be, and what's in store for the future. Part 1 covers fundamental concepts such as digital and analog communication, introduces packet switching, and explains the LAN technologies that are used in most businesses. Part 2 offers a short history of the Internet research project and how the Internet grew from the ARPANET backbone into today's global information infrastructure. Part 3 explains how the Internet works and discusses the two fundamental protocols used by all services: IP (Internet Protocol) and TCP (Transmission Control Protocol). Part 4 gives an overview of the many services available on the Internet such as browsers, search engines, email, bulletin boards, file transfer, remote desktops, wikis, blogs, and audio and video communication. In each case, the text explains how the service operates and how it uses facilities in the underlying system.

This easy-to-read textbook provides an introduction to computer architecture, focusing on the essential aspects of hardware that programmers need to know. Written from a programmer’s point of view, Essentials of Computer Architecture, Third Edition, covers the three key aspects of architecture: processors, physical and virtual memories, and input-output (I/O) systems. This third edition is updated in view of advances in the field. Most students only have experience with high-level programming languages, and almost no experience tinkering with electronics and hardware. As such, this text is revised to follow a top-down approach, moving from discussions on how a compiler transforms a source program into binary code and data, to explanations of how a computer represents data and code in binary. Additional chapters cover parallelism and data pipelining, assessing the performance of computer systems, and the important topic of power and energy consumption. Exclusive to this third edition, a new chapter explains multicore processors and how coherence hardware provides a consistent view of the values in memory even though each core has its own cache. Suitable for a one-semester undergraduate course, this clear, concise, and easy-to-read textbook offers an ideal introduction to computer architecture for students studying computer programming.

This groundbreaking historical expose unearths the lost stories of enslaved persons and their descendants who journeyed into freedom after the Emancipation Proclamation and then back into the shadow of involuntary servitude shortly thereafter in “The Age of Neoslavery.” By turns moving, sobering, and shocking, this unprecedented Pulitzer Prize-winning account reveals the stories of those who fought unsuccessfully against the re-emergence of human labor trafficking, the companies that profited most from neoslavery, and the insidious legacy of racism that reverberates today. Following the Emancipation Proclamation, convicts—mostly black men—were “leased” through forced labor camps operated by state and federal governments. Using a vast record of original documents and personal narratives, Douglas A. Blackmon brings to light one of the most shameful chapters in American history. “An astonishing book. . . . It will challenge and change your understanding of what we were as Americans—and of what we are.” —Chicago Tribune

“Tahiti is far famed yet too little known.” Thus wrote J. M. Orsmond in 1848, and the same assertion can be made in 1972. Thousands of pages had been published about Tahiti and its neighboring islands when Orsmond uttered his judgment, and tens of thousands have been published since that time, but a unified, comprehensive, and detailed description of the pre-European ways of life of the inhabitants of those Islands is yet to appear in print. The present work, lengthy as it is, makes no such claim to comprehensiveness; rather, it is concerned mainly with the social relations of those inhabitants, and it serves up only enough about their technology, their religion, their aesthetic expressions, and so forth to place descriptions of their social relations in context and render them more comprehensible. Volumes 1 and 2 of this work are a reconstruction of the Islanders’ way of life as it was believed to have been just before it began to be transformed by European influence—a period labeled the Late Indigenous Era. Volume 3 covers events in Tahiti and Mo‘orea from about 1767 to 1815—a period labeled the Early European Era.
The Great Plains, known for grasslands that stretch to the horizon, is a difficult region to define. Some classify it as the region beginning in the east at the ninety-eighth or one-hundredth meridian. Others identify the eastern boundary with annual precipitation lines, soil composition, or length of the grass. In The Big Empty, leading historian R. Douglas Hurt defines this region using the towns and cities—Denver, Lincoln, and Fort Worth—that made a difference in the history of the environment, politics, and agriculture of the Great Plains. Using the voices of women homesteaders, agrarian socialists, Jewish farmers, Mexican meatpackers, New Dealers, and Native Americans, this book creates a sweeping survey of contested race relations, radical politics, and agricultural prosperity and decline during the twentieth century. This narrative shows that even though Great Plains history is fraught with personal and group tensions, violence, and distress, the twentieth century also brought about compelling social, economic, and political change. The only book of its kind, this account will be of interest to historians studying the region and to anyone inspired by the story of the men and women who found an opportunity for a better life in the Great Plains.
