Backend Systems: Intro

Welcome to Core Components of a Backend System! Ever wonder how your apps talk to the internet?

Behind every app, there's a powerful backend system. It handles data, logic, and ensures everything runs smoothly. We'll start by understanding the basic communication.

Meet the Client

First, let's talk about the client. Think of it as the part of the system that you directly interact with.

  • Your web browser: When you visit a website.
  • Your mobile app: Like Instagram or TikTok.
  • Desktop software: Programs on your computer.

Clients are typically on your device, sending requests and displaying information.
