Description Operating Systemsprovides an understanding of contemporary operating system concepts by integrating the principles behind the design of all operating systems with how they are put into practice in the real world. Throughout, Gary Nutt provides a complete discussion of operating concepts and supplements this with real code examples, algorithms, and discussions about implementation issues. The book also includes many lab exercises that provide students with the opportunity to practice with Linux, UNIX, and Windows. Features • Provides a balanced introduction to operating system concepts by integrating OS theory with examples from real operating systems (Linux, Unix, Windows). • Student-focused writing that presents the big idea of each concept before presenting the details. • Extended lab sections between chapters include projects on: shell programming, kernel timers, memory-mapped files, TCP/IP, etc.

• Flexible arrangement of information within chapters allows professors to choose the breadth and depth of each topic. New to this Edition • Updated and extended Table of Contents, including additional material on threads, storage media, security, handheld and wireless devices, and more. More than twice as many are included to give students substantial hands-on experience with Linux, UNIX and Windows XP. • The number of exercises throughout the book has increased by more than 20%. • Best supplements of all OS books. Companion Web site includes: more labs, Unix and C reference, student study guide, testbank, solutions, suggested syllabi and more!

Files can be uploaded by multiple selection or you can pack them to any supported format (ZIP, RAR, 7Z, TAR, GZIP). Then it is possible to transform your data to any other coordinate reference system. If the coordinate system of your input data is not present or not recognized correctly, it is posible to assign the correct one. Converter also supports more than 90 others vector and rasters GIS/CAD formats and more than 3 000 coordinate reference systems.
