Introduction to Socket API
Explore the core concepts of socket programming, including socket types, addresses, and common API calls.
What are Network Sockets?
Welcome to socket programming! A socket is a crucial concept in network communication. Think of it as one endpoint of a two-way communication link between two programs running on the network.
It's like a phone jack on a wall. You plug a phone into it to connect to the phone network. Similarly, programs use sockets to connect and talk over a computer network.
Python's Socket Module
Python makes socket programming accessible through its built-in socket module. This module provides all the necessary functions and classes to create and manage sockets.
You'll typically import it at the beginning of your script. Let's see how to get started:
import socket
