Understanding Operating Systems

The fourth edition of this best-selling book blends operating systems theory and practice in an appealing, well-organized way. Its innovative two-part approach explores operating systems theory and development in the first section, and discusses the three most widely-used operating systems (MS-DOS, Windows, and UNIX) in the second. Each chapter has been updated for currency, and a brand-new chapter on System Security has been added. Students will appreciate the many examples and illustrations found within the two-color interior, as well as the overall readability of the text.
