Understanding the Digital World


Book Description

A brand-new edition of the popular introductory textbook that explores how computer hardware, software, and networks work Computers are everywhere. Some are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak personal data about us. Governments and companies increasingly use computers to monitor what we do. Social networks and advertisers know more about us than we should be comfortable with. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? In this updated edition of Understanding the Digital World, Brian Kernighan explains how computer hardware, software, and networks work. Topics include how computers are built and how they compute; what programming is; how the Internet and web operate; and how all of these affect security, privacy, property, and other important social, political, and economic issues. Kernighan touches on fundamental ideas from computer science and some of the inherent limitations of computers, and new sections in the book explore Python programming, big data, machine learning, and much more. Numerous color illustrations, notes on sources for further exploration, and a glossary explaining technical terms and buzzwords are included. Understanding the Digital World is a must-read for readers of all backgrounds who want to know more about computers and communications.







Understanding Digital Libraries


Book Description

This fully revised and updated second edition of Understanding Digital Libraries focuses on the challenges faced by both librarians and computer scientists in a field that has been dramatically altered by the growth of the Web. At every turn, the goal is practical: to show you how things you might need to do are already being done, or how they can be done. The first part of the book is devoted to technology and examines issues such as varying media requirements, indexing and classification, networks and distribution, and presentation. The second part of the book is concerned with the human contexts in which digital libraries function. Here you'll find specific and useful information on usability, preservation, scientific applications, and thorny legal and economic questions. - Thoroughly updated and expanded from original edition to include recent research, case studies and new technologies - For librarians and technologists alike, this book provides a thorough introduction to the interdisciplinary science of digital libraries - Written by Michael Lesk, a legend in computer science and a leading figure in the digital library field - Provides insights into the integration of both the technical and non-technical aspects of digital libraries




Gender and Computers


Book Description

The authors explore the proposition that computers have the potential for creating inequity in classroom education and in who is encouraged to pursue the study of computer science itself. They outline some psychological factors that have contributed to the inequality regarding gender and computers.




Understanding Digital Culture


Book Description

"This is an outstanding book. It is one of only a few scholarly texts that successfully combine a nuanced theoretical understanding of the digital age with empirical case studies of contemporary media culture. The scope is impressive, ranging from questions of digital inequality to emergent forms of cyberpolitics." - Nick Gane, York University "Well written, very up-to-date with a good balance of examples and theory. It′s good to have all the major issues covered in one book." - Peter Millard, Portsmouth University "This is just the text I was looking for to enable first year undergraduates to develop their critical understanding of the technologies they have embedded so completely in their lives." - Chris Simpson, University College of St Mark & St John This is more than just another book on Internet studies. Tracing the pervasive influence of ′digital culture′ throughout contemporary life, this text integrates socio-economic understandings of the ′information society′ with the cultural studies approach to production, use, and consumption of digital media and multimedia. Refreshingly readable and packed with examples from profiling databases and mashups to cybersex and the truth about social networking, Understanding Digital Culture: Crosses disciplines to give a balanced account of the social, economic and cultural dimensions of the information society. Illuminates the increasing importance of mobile, wireless and converged media technologies in everyday life. Unpacks how the information society is transforming and challenging traditional notions of crime, resistance, war and protest, community, intimacy and belonging. Charts the changing cultural forms associated with new media and its consumption, including music, gaming, microblogging and online identity. Illustrates the above through a series of contemporary, in-depth case studies of digital culture. This is the perfect text for students looking for a full account of the information society, virtual cultures, sociology of the Internet and new media.




Computers, Visualization, and History


Book Description

This visionary and thoroughly accessible book examines how digital environments and virtual reality have altered the ways historians think and communicate ideas and how the new language of visualization transforms our understanding of the past. Drawing on familiar graphic models--maps, flow charts, museum displays, films--the author shows how images can often convey ideas and information more efficiently and accurately than words.




The Preparation of Programs for an Electronic Digital Computer


Book Description

This is often considered the first book on computer programming. It was written for the EDSAC (Electronic Delay Storage Automatic Calculator) computer that began operation in 1949 as the world's first regularly operated stored program computer. The idea of a library of subroutines was developed for the EDSAC, and is described in this book. Maurice Wilkes lead the development of the EDSAC.




D Is for Digital
