The acronym URL stands for Uniform Resource Locator and refers to the representation that people use to locate sources and destinations on the World Wide Web. The content of the URL is called a representation because it is often more human-readable than it would be without it, which would be the protocol, typically http:// for Hypertext Transfer Protocol and the Internet Protocol address (IP address). ) represents. An IP address is made up of four three-digit numeric segments with a value between 0 and 255 and separated by periods. The URL replaces the domain name or its subdomain with the IP address. An absolute URL is a type of URL; the other type is a relative URL, and the choice to use an absolute or relative URL can most commonly come from an HREF (hypertext reference), the code used to link to another page or element.
The absolute URL contains all the possible details of a web address.
Relative means “relative to” and a relative URL indicates the location of a URL in terms of the current location. Suppose a webmaster is setting up a website and links to an image called “image.jpg” on the home page in an HREF, using a relative URL that specifies a folder at the same level within the same hierarchy and labeled “Images”. “. Since the folder with the image is on the same level, the relative address to find the image is /Images/picture.jpg. That’s all that’s needed because that’s enough information to get there from the current here. Since the relationship of “here” and “there” can change, an absolute URL is a better choice.
An absolute URL provides complete location information. Start with http:// and continue including all the details. This means that if the webmaster changed the location of the original file, an absolute URL specification would find the image, while a relative URL specification would not.
There are several other important features that make absolute URLs valuable. First, it is a unique location. While there can be many files named image.jpg in files named Images on the Internet, the absolute URL refers to only one possible location and file. Also, links going to a separate site, ie a location with a different domain name, must be designated by an absolute URL in order to be located.
