The course begins by contrasting the TCP and UDP protocols. It then describes the classic "sockets" API in detail and shows how to write clients and servers using both protocols. Techniques for achieving concurrency are covered, including multi-processing, multi-threading, and the select() system call. "C" is used as the primary implementation language but some Python examples are also presented.
