Thank you for your interest in Operating Systems. The aim of this guide is to provide additional information to assist teachers who are using the book. This material is presented in the following parts:

• Curriculum design. An outline of parts of the ACM/IEEE-CS "Computing Curricula 1991 and 2001" is given for reference throughout this guide.
• Points to emphasise and teaching hints. For each chapter we have identified important points and potential difficulties.
• Solutions to exercises and a few additional exercises. The solutions include examples of how the various designs that are discussed have been used in practice.
• Exam questions in the area that have been set at Cambridge in the past few years.
• Some overhead transparency masters.

We should like to learn from the experience of others who use Operating Systems in their teaching. In particular, it would be useful to share suggestions for practical assignments. The computing environments students use vary considerably and it is impossible to suggest universally applicable project work.

We should also be grateful for suggestions for improvements of any kind:
