Computing Concepts for Information Technology

This is an eBook available free to professors, students, and anyone who might benefit from it. I’m also planning a print edition for those who want a “real book.” That will necessarily cost a small amount of money. Each chapter has been reviewed by a peer and a subject matter expert, and proofread by at least one person who’s not me. A chapter that’s “in review” is complete and being reviewed by a subject matter expert. The links are PDF files.

Concept for cover design, with printed-circuit like tracing, title, and author.

Suggestions, comments, criticisms:

Please, please... under no circumstances upload these chapters to Chegg, Course Hero, or similar sites. I’m giving this away free to help students, and you will be able to get the current version, free, right here. Chegg and Couse Hero, especially, do not respect the rights of authors. They’ll charge students for something that’s free, then supply an out-of-date copy, so just don’t do it, OK? If you got this copy from someplace like Chegg or Course Hero, please send the link you used to, then get the current copy from the links above. Thanks!
