π What is a URL? Your Web Address Explained!

π§ Diving Deeper: What Does URL Stand For?

π A Little Bit of History: Where Did URLs Come From?

βοΈ Key Parts of a URL: What Do They Mean?
A URL might look like a jumble of letters and symbols, but each part has a job! Let's break down a common example: https://www.eokultv.com/computer-science/what-is-a-url.html

https:// (Protocol): This is like the "how to get there" rulebook. It tells your computer how to talk to the website. The 's' means it's secure! - π
www. (Subdomain): Often stands for "World Wide Web." It's like a specific neighborhood within a big city. - π‘
