00:00:02 Have you ever wondered how the apps you use every day actually work behind the scenes?
00:00:07 From ordering food to sending messages or streaming videos, there's a lot happening under the hood that most people never see.
00:00:15 While the front end looks sleek and interactive, it's the back end that keeps everything running, handling data, security,
00:00:23 and performance.
00:00:24 And if you've thought about getting into backend development, you might feel like it's too complex with servers, databases,
00:00:31 APIs, and authentication to figure out.
00:00:33 But here's the thing, it's not as complicated as it seems.
00:00:37 And today, you'll learn it all.
00:00:39 So let's break it down.
00:00:41 The web is split into two parts, the frontend and the backend.
00:00:45 The front end is all about user experience with three key parts.
00:00:50 The user, which is you, me, or anyone interacting with the app, whether scrolling through Instagram, reading a blog, or watching one YouTube video after another.
00:01:00 The client, which is the device or an app like your browser that connects us to the web.
00:01:06 And finally, there's the interface, the layout, and the design we interact with, built with Next.js, React, or good old HTML,
00:01:15 CSS, and JavaScript.
00:01:17 Think of the client, your laptop, phone, or tablet, as a bridge connecting you to the internet.
00:01:23 But where does that information come from?
00:01:26 And how does it reach you?
00:01:28 That's where servers come in.
00:01:29 A server is just a powerful computer designed to store, process, and send data.
00:01:35 It's a real machine, sitting in a data center somewhere that you can own or rent through services like AWS.
00:01:43 On the server, we store the backend code, the logic that handles everything from processing data to managing users and interacting with databases.
00:01:52 So, how does your device, the client, communicate with a random server to get things done?
00:01:58 Well, here's how.
00:02:00 Well, first, you make a request.
00:02:02 When you visit a website, search for something, or log into an app, your device sends a request over the internet.
00:02:09 Then, that request reaches a server which processes it.
00:02:12 This server could hold website data, user accounts, or even real-time Nvidia stock prices when DeepSeek got released.
00:02:20 And finally, the server responds.
00:02:23 Once it processes your request, it sends back the data, whether it's a webpage, search results, or your messages.
00:02:29 So, in the next lesson, let's dive deeper into how all of this works under the hood.
