所谓“移植”，就是使一个实时内核能在其它的微处理器或微控制器上运行。 尽管大部分μC/OS-II的代码是用C语言编写的，但是在编写与处理器硬件相关的代码时还是不得不使用汇编语言。 移植的主要工作就是编写这些与处理器硬件相关的代码。 操作系统的移植大体可以分为两个层次： 跨体系结构的移植 针对特定处理器的移植

This book’s primary goal is to help you prepare to take and pass Microsoft’s exam number 70-290, Managing and Maintaining a Microsoft Windows Server 2003 Environment. Our secondary purpose in writing this book is to provide exam candidates with knowledge and skills that go beyond the minimum requirements for passing the exam, and help to prepare them to work in the real world of Microsoft computer networking.

When the authors of this book asked me to write the foreword of their work on the digital enterprise, I immediately thought that it was one more document on a fashionable topic in the technology and the business world of the 21st Century often addressed by consulting firms, some of which have aspired to become experts on the subject. However, a more careful observation reveals that an issue more important than the sole subject of the digital enterprise is: “Is your company fully operational?”, because this is the real topic.

In Helsinki during a visiting lecture, an internationally well-known professor in communica- tionssaid,‘Inthecommunicationssocietywehavemanagedtoconvertourproposalsandideas to real products, not like in the control engineering society. They have very nice papers and strong mathematics but most of the real systems still use the old PID controllers!’. As our background is mainly in control as well as communications engineering, we know that this thought is not very accurate. We agree that most of the practical controllers are analog and digital PID controllers, simply because they are very reliable and able to achieve the required control goals successfully. Most of the controllers can be explained in terms of PID. The reasons behind this impressive performance of PID will be explained in Chapter 2.

Internet of Things (IoT) [26] is a new networking paradigm for cyber-physical systems that allow physical objects to collect and exchange data. In the IoT, physical objects and cyber-agents can be sensed and controlled remotely across existing network infrastructure, which enables the integration between the physical world and computer-based systems and therefore extends the Internet into the real world. IoT can find numerous applications in smart housing, environmental monitoring, medical and health care systems, agriculture, transportation, etc. Because of its significant application potential, IoT has attracted a lot of attention from both academic research and industrial development.
