URL (Uniform Resource Locator)

[yoo-ahr-el]

A URL (Uniform Resource Locator) is a standardized address format used to identify and locate resources on the internet. It serves as a unique identifier that tells web browsers exactly where to find specific web pages, images, documents, or other files on the World Wide Web.

Anatomy of a URL

A typical URL consists of several components:

Protocol: The scheme that indicates how the browser should communicate (e.g., “https://”)
Domain Name: The website’s address (e.g., “www.example.com”)
Path: The specific location of a page or resource (e.g., “/blog/article”)
Parameters: Optional values that pass information (e.g., “?id=123”)
Fragment: A specific section within a page (e.g., “#section1”)

Types of URLs

Absolute URLs

These contain all necessary information to locate a resource, including the protocol and domain name. They work independently of where they’re used:

https://www.example.com/products/item1

Relative URLs

These specify a path relative to the current location, omitting the protocol and domain:

/products/item1
