    The Internet allows computers thousands of miles apart to exchange information through programs such as Web browsers, and nearly all of these programs gain access to network communication services through the sockets programming interface. TCP/IP Sockets in C: Practical Guide for Programmers is a quick and affordable way to gain the knowledge and skills needed to quickly develop sophisticated and powerful web-based applications. Written by two experienced networking instructors, the book s focused, tutorial-based approach enables the reader to master the tasks and techniques essential to virtually all client-server projects using sockets in C. Programming concepts are introduced through simple, real-world examples, and are accompanied by line-by-line code commentary that describes the purpose of each part of the program. The book s companion website also contains myriad employable examples of command-based source code discussed throughout the text
