Broadcast media, such as satellite, ground radio, and multipoint cable channels, can easily provide full connectivity for communication among geographically distributed users. One of the most important problems in the design of networks (referred to as packet broadcast networks) that can take practical advantage of broadcast channels is how to achieve efficient sharing of a single common channel.
This book provides students with a deep, working understanding of the essential concepts of programming languages. Most of these essentials relate to the semantics, or meaning, of program elements, and the text uses interpreters (short programs that directly analyze an abstract representation of the program text) to express the semantics of many essential language elements in a way that is both clear and executable. The approach is both analytical and hands-on.
In the early days of computer science, the interactions of hardware, software, compilers, and operating system were simple enough to allow students to see an overall picture of how computers worked. With the increasing complexity of computer technology and the resulting specialization of knowledge, such clarity is often lost.
It has been more than twenty years since desktop publishing reinvented design, and it's clear that there is a growing need for designers and artists to learn programming skills to fill the widening gap between their ideas and the capability of their purchased software. This book is an introduction to the concepts of computer programming within the context of the visual arts.
What is the status of the Free and Open Source Software (F/OSS) revolution? Has the creation of software that can be freely used, modified, and redistributed transformed industry and society, as some predicted, or is this transformation still a work in progress? Perspectives on Free and Open Source Software brings together leading analysts and researchers to address this question, examining specific aspects of F/OSS in a way that is both scientifically rigorous and highly relevant to real-life managerial and technical concerns.
Open source software is considered by many to be a novelty and the open source movement a revolution. Yet the collaborative creation of knowledge has gone on for as long as humans have been able to communicate.
After completing this self-contained course on server-based Internet applications software, students who start with only the knowledge of how to write and debug a computer program will have learned how to build web-based applications on the scale of Amazon.com. Unlike the desktop applications that most students have already learned to build, server-based applications have multiple simultaneous users. This fact, coupled with the unreliability of networks, gives rise to the problems of concurrency and transactions, which students learn to manage by using the relational database system.
The goal of The Reasoned Schemer is to help the functional programmer think logically and the logic programmer think functionally. The authors of The Reasoned Schemer believe that logic programming is a natural extension of functional programming, and they demonstrate this by extending the functional language Scheme with logical constructs—thereby combining the benefits of both styles. The extension encapsulates most of the ideas in the logic programming language Prolog.
Software has gone from obscurity to indispensability in less than fifty years. Although other industries have followed a similar trajectory, software and its supporting industry are different. In this book the authors explain, from a variety of perspectives, how software and the software industry are different—technologically, organizationally, and socially.
Uncertainty is a fundamental and unavoidable feature of daily life; in order to deal with uncertaintly intelligently, we need to be able to represent it and reason about it. In this book, Joseph Halpern examines formal ways of representing uncertainty and considers various logics for reasoning about it.
