A Uniform Resource Locator, commonly abbreviated as URL, is a reference or address used to access resources on the internet. It provides the means for retrieving any piece of data or content online, which can range from web pages and images to videos and downloadable files. A URL is composed of various parts, including a protocol such as HTTP or HTTPS, which dictates how data is transferred over the web; a domain name that specifies the location of the web server hosting the content; and often a path, which includes a directory and file structure to pinpoint the exact resource within the server. Additionally, a URL may contain a port number, parameters, or query strings that provide further details or instructions for the server to process the request. In essence, a URL serves as a unique identifier for every piece of content on the web and is essential for navigating the vast digital landscape of the internet.
