Universal Resource Locator (URL)
A Universal Resource Locator (URL) is a unique address that identifies a specific web page or file on the Internet. It is used to locate web pages, images, videos, and other online content. URLs are composed of several parts, including a protocol, domain name, path, and query string. URLs are used to access web pages, download files, and access other online resources.
History of the Term
The concept of a URL was first proposed in 1989 by Tim Berners-Lee, the inventor of the World Wide Web. He proposed a system of universal resource identifiers (URIs) that would allow users to access any resource on the Internet. The URL was one of the first URIs to be developed and is still the most widely used. It is a standardized way of identifying web pages and other online resources.
