Computer Science: An Overview uses broad coverage and clear exposition to present a complete picture of the dynamic computer science field. Accessible to students from all backgrounds, Glenn Brookshear uses a language-independent context to encourage the development of a practical, realistic understanding of the field. An overview of each of the important areas of Computer Science (e.g. Networking, OS, Computer Architecture, Algorithms) provides students with a general level of proficiency for future courses.

The Eleventh Edition features two new contributing authors (David Smith — Indiana University of PA; Dennis Brylow — Marquette University), new, modern examples, and updated coverage based on current technology.

This unique book offers a readable survey of computer science, covering a wealth of topics and equipping the reader with an understanding of the scope of the science as well as the terminology in the field. This new edition contains new sections reflecting the growing importance of object-oriented methodologies in programming and database design.

Editorial Reviews

For computer science majors and minors in the early stages of their college careers, many of whom mistakenly equate programming and computer science, and for students of other disciplines who want computer literacy beyond the ability to manipulate a particular program or do a little elementary programming. Exposes such students to the breadth of the subject, discussing machine architecture--data storage and manipulation; software--algorithms, programming languages, and software engineering; data organization; and the potential of algorithmic machines.
