Answer:
A URL (uniform resource locator) is a unique identifier used to locate a resource on the Internet. It is also referred to as a web address.URLs consist of multiple parts -- including a protocol and domain name -- that tell a web browser how and where to retrieve a resource.
Explanation:
A URL is nothing more than the address of a given unique resource on the Web. In theory, each valid URL points to a unique resource. Such resources can be an HTML page, a CSS document, an image, etc. In practice, there are some exceptions, the most common being a URL pointing to a resource that no longer exists or that has moved. As the resources represented by the URL and the URL itself are handled by the Web server, it is up to the owner of the web server to carefully manage that resource and its associated URL.
