The information society, where information and intelligence are the key drivers of personal, business and national success, has arrived. Data communication is principle enabler of the rapid information exchange and will become more important than the use of computers themselves in the future. Successful users of data communications gain significant competitive advantage in the market place. In the future, it is hoped that communication networks will be pervasive in the safe way as electricity is today. Video, voice, data communication network will be integrated so that any communication network will transmit and deliver any type of data. A multitude of new information services will develop on these networks. The study of data communication will become a basic tool that can be used during one’s lifetime as this would incorporate their data communication knowledge into several careers such as circuit designer, programmer, business system application developer, communication specialist and business manager. It is hoped that the students will be immensely benefited if they learn the basics from this text book, for the remainder of their life.
