TCP/IP Sockets in C#

Preface

For years, college courses in computer networking were taught with little or no “hands on” experience. For various reasons, including some good ones, instructors approached the principles of computer networking primarily through equations, analyses, and abstract descriptions of protocol stacks. Textbooks might include code, but it was unconnected to anything students could get their hands on. Perhaps in an ideal world this would suffice, but we believe that students learn better when they can see (and then build) concrete examples of the principles at work. Fortunately, such examples abound today. The Internet has become a part of everyday life, and access to its services is readily available to most students (and their programs).
