🪜 Step 1: What Is a Browser?

A browser (short for web browser) is a software application that allows you to access and view websites on the internet.

It’s like your window to the web — helping you connect to online information, videos, apps, and more.

✅ Example:
When you type www.google.com into Chrome or Safari, your browser loads that website and displays it for you.

💻 Step 2: How Does a Browser Work?

Here’s what happens behind the scenes when you open a website:

1. You type a website address (URL) into the browser’s address bar.

2. The browser connects to the website’s server.

3. The server sends back data (HTML, CSS, JavaScript).

4. The browser processes this data and shows you the final web page.

💡 Think of it like this:
The browser is your interpreter between you and the internet — translating code into the websites you see and use every day.
