HTTP Basics.
HTTP stands for HyperText Transfer Protocol. Since the dawn of the Internet, HTTP has been playing a key role in delivering the content worldwide. In simple terms, you can consider HTTP as a set of rules for transferring files. If you notice carefully while browsing a website, you will find that there are files (like images, text, video, etc.) that display in your browser directly, while others (like zip, rar, etc.) get downloaded. Think about it for a second: why does one file get downloaded, while others get rendered or played in the browser directly? The answer is simply because of how the web server and web client (typically your web browser) are interacting behind the scenes. You can think of HTTP as a language in which the web server and a web client communicates. As a website user, you are simply consuming the visual elements that the website creators planned for you. Hence, unless you are curious, you will hardly notice the underlying communication. It is almost like using a refrigerator. You just need to know that it is used to preserve your food by keeping it cold and what goes in normal comes out chilled. You would hardly ever bother about how it actually works.
