Let's get down to the fundamentals of web applications! Come with me as we explore what makes a web application tick.

HTTP and Web Servers

HTTP (Hypertext Transfer Protocol) is the backbone of communication between browsers and servers. When I type a a web page or address in my browser, it sends an HTTP request to the and then, the web server responds with an HTTP response containing the website data. Web servers store and serve this data, just like a pharmacist waiting to serve customers.

HTML, CSS, and JavaScript

Now, web applications are made of three key components: HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript. HTML is like the skeleton static web application, providing structure, while CSS is the skin, handling styling and layout. JavaScript, on the other hand, adds some magic to the mix of static web apps, by providing interactivity and dynamic behavior of browser interface.

Markup Language and Document Types

Remember how I mentioned that HTML is a type of markup language? It means that it uses tags to describe and structure content. The most crucial tag is the DOCTYPE declaration found at the top of an HTML document. It tells browsers which version of HTML is being used, like waving a flag to say, "Hey, I'm speaking HTML5!"

Front-End Development

As we've seen, the visual aspect of a web application is a combination of HTML, CSS, and JavaScript. This is the domain of-end development. It's all about what I see and interact with when I visit a website.

Back-End Development

Finally, there's back-end development, the unsung hero working behind the scenes. In this realm, server-side languages like PHP, Python, and Ruby process data, create apps, interact with databases, and handle user authentication. Back-end web development allows the whole operating system to run smoothly and efficiently, like the gears in a clock. In Essence, backend development is responsible for the server-side components that power web applications and ensure they work efficiently, securely and reliably.
