PyNet

This document provides a tutorial on network programming with Python. It begins with an overview of key network concepts like MAC addresses, IP addresses, ports, connectionless vs connection-oriented communication, and clients and servers. It then analyzes a sample client/server program written in Python to demonstrate how they communicate. It discusses the role of the operating system in managing connections and distinguishing between multiple simultaneous connections. Finally, it covers additional topics like sending lines of text over TCP connections and dealing with asynchronous network inputs.
