Techniques are illustrated step-by-step using full color photography and screen prints throughout, together with concise, easy to follow text from an established expert in the field, provide a comprehensive guide to computer systems.

A presentation of the central and basic concepts, techniques, and tools of computer science, with the emphasis on presenting a problem-solving approach and on providing a survey of all of the most important topics covered in degree programmes. Scheme is used throughout as the programming language and the author stresses a functional programming approach to create simple functions so as to obtain the desired programming goal. Such simple functions are easily tested individually, which greatly helps in producing programs that work correctly first time. Throughout, the author aids to writing programs, and makes liberal use of boxes with "Mistakes to Avoid." Programming examples include: * abstracting a problem; * creating pseudo code as an intermediate solution; * top-down and bottom-up design; * building procedural and data abstractions; * writing progams in modules which are easily testable. Numerous exercises help readers test their understanding of the material and develop ideas in greater depth, making this an ideal first course for all students coming to computer science for the first time.

Why so few African American and Latino/a students study computer science: updated edition of a book that reveals the dynamics of inequality in American schools. The number of African Americans and Latino/as receiving undergraduate and advanced degrees in computer science is disproportionately low. And relatively few African American and Latino/a high school students receive the kind of institutional encouragement, educational opportunities, and preparation needed for them to choose computer science as a field of study and profession. In Stuck in the Shallow End, Jane Margolis and coauthors look at the daily experiences of students and teachers in three Los Angeles public high schools: an overcrowded urban high school, a math and science magnet school, and a well-funded school in an affluent neighborhood. They find an insidious “virtual segregation” that maintains inequality. The race gap in computer science, Margolis discovers, is one example of the way students of color are denied a wide range of occupational and educational futures. Stuck in the Shallow End is a story of how inequality is reproduced in America—and how students and teachers, given the necessary tools, can change the system. Since the 2008 publication of Stuck in the Shallow End, the book has found an eager audience among teachers, school administrators, and academics. This updated edition offers a new preface detailing the progress in making computer science accessible to all, a new postscript, and discussion questions (coauthored by Jane Margolis and Joanna Goode).

The essential manual "Exploring Computer Systems: From Fundamentals to Advanced Concepts" takes readers on a thorough tour of the world of computer systems. This book offers a thorough examination of computer systems, starting with the fundamentals and advancing to complex concepts. The book's excellent basis in computer architecture and components at the outset makes it understandable for both newcomers and seasoned IT experts. The basic concepts of hardware, software, and their relationships are covered, enabling readers to comprehend how contemporary computer systems operate within. Readers delve into the complexities of operating systems, including as process management, memory management, and file systems, as they move through the chapters. The author is succinct and straightforward. These complicated subjects are demystified by the author's succinct and simple explanations, making them understandable to readers of all skill levels. This book's covering on networking and communication protocols is one of its best qualities. It offers a thorough review of computer networking and communication in local and wide-area networks, illuminating terms like TCP/IP, routing, and security. The fascinating worlds of virtualization and cloud computing are also highlighted in the book. The impact of virtual machines and cloud services, which have transformed the IT environment and increased computing flexibility, scalability, and affordability, is explained to readers.

Computers are the most complex machines that have ever been created. Very few people really know how they work. This book tells you how they work; no technical knowledge is required. It explains the operation of a simple, focusing on computer hardware and software related. This book shows that computer hardware isn’t so complicated and can be easily understood by anyone. This is a short book, but it must be studied carefully. This means that you will have to read some parts more than once to understand them. Get as far as you can. You will be much more knowledgeable about how computers work when you are done than when you started, even if you are not able to get through the whole text. This is a technical book though it is aimed at a non-technical audience. Though this book takes considerable effort to understand, it is very easy for what it explains. After you have studied this book, it will seem simple if you go back and read it.
