Summary

At this point, we have covered the various I/O models available in Winsock. These models allow applications to tailor Winsock I/O according to their needs, from simple blocking I/O to high-performance completion port I/O for the maximum throughput possible. Up to this point, you have learned about available transport protocols, socket creation attributes, creating a basic client/server application, and other fundamental Winsock topics.
