A Balanced Introduction to Computer ScienceThis carefully written, balanced book teaches the most important concepts in computing and computer science while providing enough programming depth to enable understanding about how people work with computers. Taking advantage of today's interest in and familiarity with the Web, the book contains experimental problems using Web-based tools; enabling readers to learn the fundamentals of programming by developing their own interactive Web pages. Beginning with an introduction, overview, and the basics of computers, the book proceeds with comprehensive chapters on HTML and Web pages, the Internet, JavaScript and Web page creation, the history of computers, abstraction and user-defined functions, algorithms and programming languages, event-driven programming, conditional execution, data representation, conditional repetition, JavaScript strings, and transistors and integrated circuits. This book can serve as an excellent reference resource for those entering the computer job market: programmers, Web site and Web page designers, and technical support staff. |
