URL (Uniform Resource Locator)

 URL (from Uniform Resource Locator) is a standardized address used to specify the exact location of a resource on the internet, such as a website, page, image, file, or any other online resource.

Using a URL, browsers can locate and display web pages for users.

🔧 Structure of a URL:

A URL typically consists of the following components:

Example URL:
https://www.example.com/products?id=123#details

🌍 A Simple URL Example:

• Protocol: https://

• Domain Name: www.example.com

• Path: /products

• Query: ?id=123

• Fragment: #details

✅ Advantages of Using URL:

• Simple and Clear: URLs make it easy to find a specific resource.

• Unique Addressing: Every web page or file has its own unique URL.

• Security: The https protocol ensures secure data transfer.

• Quick Access: Users can directly access a web page by entering the precise URL.

🔄 URL vs. IP Address:

🧠 How a URL Works:

1. The user enters the URL in a browser.

2. The browser sends a request to the DNS (Domain Name System) to convert the domain name to an IP address.

3. The browser sends the request to the server and receives the resource (e.g., a web page).

4. The browser displays the page to the user.

🚀 Conclusion:

URL is a system of addressing in the internet that helps identify the exact location of resources like websites, images, files, and more. Properly structured URLs make it easier to navigate and access online resources.
