This video tutorial covers the fundamentals of network programming, focusing on Java's support for networking. It begins with an introduction to basic networking concepts and the ISO model, followed by practical coding exercises to create UDP and TCP ECHO servers. The tutorial also explores higher-level protocols like SMTP, POP3, IRC, FTP, and SSH, and discusses Java's asynchronous API for high-performance applications. The video concludes with a preview of the next tutorial, which will focus on HTTP.
