The 436 pages of six books (integrated into one tome) include Information Technology, Management, Artificial Intelligence, Internet, Expert Systems, Systems Analysis, Computing, Risk Management, and Change Management. In writing this volume, the author took into consideration the advance of today's information technology and computing in general, the principles of work and leisure alike, factory and business operations, networking, defence, medicine, education and the domestic environment. Also, the social concerns that computers and their systems influence our attitudes to privacy, and employment. Although the world of computing became smaller with new ultra-small computing systems, equipped with wireless networking systems worldwide, the reader can appreciate that the construction of such systems is as complex as a house built in a swamp. It does, therefore, require careful planning and design. Just as a house must have an architect's plan, so does a system.
