Python's socket module

Python's socket module provides tools to connect computers and devices over a network, allowing them to send and receive data. It acts like a telephone system, where sockets are the endpoints—similar to phone lines—used to establish communication channels. You can create sockets to connect to servers, send messages, or receive information. This module underpins many internet-based applications, such as websites, chat programs, and data sharing systems. It supports various protocols like TCP and UDP, enabling reliable or fast, connectionless data transfer. Essentially, it offers the foundational building blocks for network communication in Python programs.
