URL - Uniform Resource Locator
URL is the abbreviation of Uniform Resource Locator and is defined as the global address of documents and other resources on the World Wide Web. To visit this website, for example, you'll go to the URL www.webopedia.com.
We all use URLs to visit webpages and other resources on the web. The URL is an address that sends users to a specific resource online, such as a webpage, video or other document or resource. When you search Google, for example, the search results will display the URL of the resources that match your search query. The title in search results is simply a hyperlink to the URL of the resource.
What Are the Parts of a URL?
The first part of the URL is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes.
For example, the two URLs below point to two different files at the domain webopedia.com. The first specifies an executable file that should be fetched using the FTP protocol; the second specifies a webpage that should be fetched using the HTTP protocol:
Web Address is a URL with HTTP/HTTPS
The term "web address" is a synonym for a URL that uses the HTTP or HTTPS protocol. The Uniform Resource Locator (URL) was developed by Tim Berners-Lee in 1994 and the Internet Engineering Task Force (IETF) URI working group. Today, the format of the URL has not changed. The URL format is specified in RFC 1738 Uniform Resource Locators (URL).
In Programming: The URL Class
Note that in object-oriented programming, such as Java, programs can use a class (a category of objects) called URL. You can create a URL object to represent the URL address. See Java Tutorials: Working with URLs in the Related Links section below for additional information on using the URL object in a Java program.
