The browser's first task is to find and retrieve the desired information resource. The location of each information resource on the [[web]] is indicated by an address, called a [[Uniform Resource Locator]] (URL). When the URL is entered into the browser's [[address bar]], the browser sends a request to the [[website]]. The request is processed and answered by the [[web server]] running the website, which sends a copy of the corresponding information resource (such as a [[web page]]) back to the browser. | The browser's first task is to find and retrieve the desired information resource.
