Summary

This chapter introduced two important concepts useful in network programming: threading and the asynchronous pattern. These asynchronous programming techniques allow you to design more flexible applications so that you can do multiple things at the same time in one application. This flexibility is important because you can develop a networking application that can service a user interface while it processes I/O on a network, which makes the user experience much better. Many of the remaining chapter discussions and samples will use these asynchronous programming techniques.
