Section 1 of 5
Introduction
In the previous module, you learned how computers find each other using IP addresses and domain names. You learned about DNS, ports, and protocols. Now it is time to learn about the language they use to talk to each other.
That language is HTTP. It stands for Hypertext Transfer Protocol, and it is the foundation of all web communication.
In this module, you will learn how HTTP works, how requests and responses are built, and how encryption and security fit into the picture. These are essential topics for understanding web applications.
