URL?

Evolution of a name based URL is a big story. Yet, What is a URL?

URL – Universal Resource Locater.

Let’s start from our home, If someone needs to meet us/post us, they need an address that leads them/their post to us. Here people search you so they need your address.

In the same way, When you provide a Resource via Internet, It needs some address to be provided so that people can access your resource easily. That address may be called URL aka Web address.
