URL stands for Uniform Resource Locator. In simple terms, a URL is a website address and many people use the two terms interchangeably.

Tim Berners-Lee, who was the inventor of the World Wide Web in 1989, defined a format for Uniform Resource Locators in 1994. This format created a path to a website, where a typical URL had a protocol (http), hostname (example: company name), and a file name (welcome.html).
