Network Programming (C++)

Build high-performance network applications. Master Socket programming, TCP/UDP internals, and Asynchronous I/O using C++.

Network programming is the foundation of the internet. This course teaches you to build clients and servers from scratch using C++. You will master the Berkeley Sockets API, understand the nuances of TCP vs UDP, and implement custom application protocols. We dive into high-performance I/O models like Select, Poll, Epoll, and IO_URING to handle thousands of concurrent connections. Perfect for developers building game servers, proxies, or high-frequency trading gateways.
