breadth-first overview of the full range of topics in this dynamic discipline: algorithms, hardware design, computer organization, system software, language models, programming, compilation, theory of computation, applications, networks, artificial intelligence, and the impact of computers on society. The authors present these topics in the context of a big picture, - six-layer hierarchy of abstractions - starting with the algorithmic foundations of computer science, and working upward from low-level hardware concepts through virtual machine environments, languages, software, and applications programs to the social issues raised by computer technology. Each layer in the hierarchy builds on ideas and concepts presented earlier. An accompanying lab manual provides exploratory lab experiences tied to the text material. The Second Edition features the use of C++ for teaching the basics of programming, with a C++ compiler provided with the accompanying lab manual. This compiler includes a graphics library that students use to create shapes and images as part of a new section in Chapter 7 on "Graphical Programming."
