Computers and Information Systems: An Introduction
Presents the standard introductory computer concepts in a way that gives the instructor almost complete flexibility in the order of presentation. The text covers all the important topics and allows the instructor to define the sequence of presentation and teach the chapters in any order. Advanced topics boxes allow instructors to stimulate the more advanced students without overwhelming the beginning students. Feature boxes supplement and illustrate specific chapter topics on social and ethical issues, real world examples such as surge protection and care of diskettes, where information technology is going, and more. Spotlights vignettes between chapters include additional information on topics such as the Internet, computer security, and ethics. Additional Internet coverage is interspersed throughout the text, along with Internet projects at the end of each chapter and an appendix of interesting USENET and WWW addresses.
