How Websites Appear on Your Screen

We click on links, fill out forms, and watch videos, all thanks to those colourful pages call websites. But have you ever wondered how they actually work? What goes on behind the scenes to bring the internet to your finger tips. Understanding how websites work might seem daunting at first, but with few analogies and clear explanations, it becomes a lot easier. Let’s break down the process step by step.

Ordering Your Favourite Ice cream: Client-Server Model

Imagine walking into an ice cream shop and ordering your favourite ice cream. Here you are the client, browsing the menu and making a request. The shopkeeper and the shop, acts as the server, preparing your order and serving it to you.

Similarly, when you browse the web, your web browser (like Chrome, Firefox or Safari) is the client. It’s how you interact with the vast world of websites. The server is like a powerful and always-on computer that stores the website’s files like - its images, text, videos and code ready to serve them up when requested.

Finding the Right Restaurant: URLs and DNS

Obviously, you need to know which ice cream shop you want to go to! This is where the URL (Uniform Resource Locator) comes in. It’s the address you type into your browser, like “google.com” . Think of it as the ice cream shop’s name and location combined.

But now the question is how does your browser find the right server with just a name? That’s where DNS (Domain Name System) steps in, acting like a giant phone book for the internet. When you type a URL, your browser contacts a DNS server, which gives a human-readable domain name (like “google.com”) into the server’s unique IP address (a numerical identifier, like a phone Number).

The Secret Recipe: HTML and Web Page Structure

Now, let's step behind the counter at the ice cream shop! Just as an ice cream maker needs a recipe to create a delicious mango flavoured ice cream, websites use a language called HTML (HyperText Markup Language) to structure their content.

Imagine HTML as a set of instructions for the browser:

<!DOCTYPE html>
<html>
<head>
    <title>Our Ice Cream Shop</title>
</head>
<body>
    <h1>Welcome to Scoops & Smiles!</h1>
    <p>We serve the best ice cream in town!</p>
    <img src="icecream.jpg" alt="Delicious Ice Cream">
    <h2>Our Flavours:</h2>
    <ul>
        <li>Mango</li>
        <li>Chocolate</li>
        <li>Vanilla</li>
        <li>Strawberry</li>
    </ul>
</body>
</html>

<!DOCTYPE html>: Tells the browser this is an HTML5 document.
<html>: The root element of the page (the entire shop).
<head>: Contains meta-information about the page (like the shop's sign).
<title>: Sets the title that appears in the browser tab (the shop's name).
<body>: Contains the visible content of the page (everything inside the shop).
<h1>: A main heading (the shop's main sign).
<p>: A paragraph of text (a description of the shop).
<img>: An image (a picture of the ice cream).
<h2>: A subheading (a category of items).
<ul>: An unordered list (a list of ice cream flavors).
<li>: A list item (an individual flavour).

This structured code is what allows your browser to render a visually appealing and organised web page.

Placing Your Order: HTTP Requests and Response

Back to our ice cream shop! Once you’ve decided what to order, you let the server know by placing your order. This is similar to your browser communicates with the web server using HTTP requests.

when you click on a link or type a URL, your browser sends a request to the server, saying, “Hey, can I please have the content for this page?”. The server then responds by sending back the requested data - the website’s files in an HTTP response.

It’s like the waiter or the shop owner taking your order to behind the counter and bring back your delicious ice cream! Same way your browser then takes the data and uses HTML, CSS (for styling), and Javascript (for interactive elements) to render the complete web page on your screen.

A Splash of Style with CSS

Let’s be honest, presentation matters! You wouldn’t want your ice cream just dumped on the table or your hand, would you? That’s where CSS (Cascading Style Sheets) comes in.

Think of CSS as the ice cream shop’s interior decorator. It takes care of the website’s look and feel - its colours, fonts, layout, and responsiveness across different devices. CSS makes websites visually appealing and engaging.

Adding Some Spice with JavaScript

what if in the shop you want to request extra napkins or ask for the WiFi password? That’s where JavaScript comes in, making websites interactive and dynamic.

JavaScript is like the friendly waiter who takes care of your additional requests, making your dining experience smoother. It allows you to interact with the website elements, validate forms, play games, and much more. JavaScript brings websites to life!

There you have it—the magic of websites broken down step by step! Next time you’re browsing the web, take a moment to appreciate the intricate dance of clients, servers, URLs, DNS, HTML, and HTTP that makes it all possible. In the next post, we’ll dive into the layers of the Internet. Stay tuned! 🙌
