This text, Applied Operating Systems Concepts, is based on the text Operating System Concepts, 5/e (1998) by Abraham Silberschatz and Peter Baer Galvin. Like OSC, Applied provides a clear description of the concepts that underlie operating systems. One of the key differences is that Java is used to present many of these ideas and included are numerous examples that pertain specifically to popular operating systems such as UNIX, Solaris 2, Windows NT, the Apple Macintosh OS, IBM's OS/2 and Linux. The advent of Java technology has given the authors an excellent vehicle to illustrate many of the most important concepts in modern operating systems today. Topics like multi-tasking, CPU scheduling, process synchronization, deadlock, security, and distributed systems lend themselves very well to demonstrations using Java technology. Applied examples of operating systems concepts using Java allows students to better understand the many operating systems concepts using a real language rather than a pedagogic tool. The book: uses numerous examples of current operating systems including Solaris, Windows NT, and Linux; provides a chapter devoted to threads - as threads are an increasingly important topic in an operating systems curriculum the authors have devoted an entire chapter to this topic; and provides a Java-based thread scheduler - the thread scheduler allows students to better understand how the operating system schedules threads
