PREFACE
This volume is an instructor’s manual for the First Edition of Applied Operating-System Concepts
by Abraham Silberschatz, Peter Baer Galvin, and Greg Gagne. It consists of answers to the
exercises in the parent text. In cases where the answer to a question involves a long program,
algorithm development, or an essay, no answer is given, but simply the keywords “No Answer”
are added.
Although we have tried to produce an instructor’s manual that will aid all of the users of
our book asmuch as possible, therecan always be improvements (improvedanswers, additional
questions, sampletest questions, programming projects, alternative orders ofpresentation of the
material, additional references, and so on). We invite you, both instructors and students, to help
us in improving this manual. If you have better solutions to the exercises or other items which
would be of use with Applied Operating-System Concepts, we invite you to send them to us for
consideration in later editions of this manual. All contributions will, of course, be properly
credited to their contributor.
