URL

URL stands for Uniform Resource Locator. Depending on your background, there’s a good chance you’ve never heard anyone say the acronym’s full phrase out loud. It speaks to how fundamental the concept is to the structure of the modern world.
Like the name suggests, a URL identifies the location of something that lives on the internet, including servers and websites, and we use them to give our browsers instructions on where to go. They’re “uniform” because they’re all structured the same way. It’s the same concept as an address for a building which tells the Postal Service where to take your mail.
