Complete Idiot’s Guide to Computer Basics, 5th Edition [EPUB ebook] 

The fifth edition of The Complete Idiot’s Guide to Computer Basics places the reader in charge of the computer, rather than the other way round, and places the focus on software troubleshooting rather than hardware techno-babble. The reader wants to do something practical with his or her computer — this book shows them how. It covers basic office programs and how to manage photo, video and music files. It offers advice on safe web-surfing, including coverage of newsgroups, message boards and mailing lists. There are new green computing initiatives that help protect the environment. It includes maintenance and upgrading information.
