简介:
I wrote this text for students of computer science as well as students from
other disciplines. As for computer science students, most begin their studies
with the illusion that computer science is programming, Web browsing, and
Internet file sharing since that is essentially all they have seen. Yet computer
science is much more than this. In turn, beginning computer science students
need exposure to the breadth of the subject in which they are planning
to major. Providing this exposure is the theme of this book. It gives students
an overview of computer science—a foundation from which they can appreciate
the relevance and interrelationships of future courses in the field. This
survey approach is, in fact, the model used for introductory courses in the
natural sciences.
This broad background is also what students from other disciplines need if
they are to relate to the technical society in which they live. A computer science
course for this audience should provide a practical, realistic understanding of the
entire field rather than merely an introduction to using the Internet or training
in the use of some popular software packages. There is, of course, a proper place
for training, but this text is about educating.
Thus, while writing this text, maintaining accessibility for nontechnical students
was a major goal. The result is that previous editions have been used successfully
in courses for students over a wide range of disciplines and educational
levels, ranging from high school to graduate courses. This eleventh edition is
designed to continue that tradition.
