The authority of a URI is the section that comes after the scheme and before the path. It may have up to three parts: user information, host, and port.
The fragment of a URI is the last part of the URI, starting with the # character. It is used to identify a specific part of the resource, such as a section of a document or a position in a video. The fragment is not sent to the server when the URI is requested, but it is processed by the client (such as the browser) after the resource is retrieved.
The path of a URI is the section that comes after the authority.
It contains data, usually organized in hierarchical form, to identify a resource within the scope of the URI's scheme and naming authority.
The query of a URI is the section that comes after the path.
It contains non-hierarchical data to identify a resource within the scope of the URI's scheme and naming authority along with data in the path component.
The scheme of a URI is the first part of the URI, before the : character.
It indicates which protocol the browser must use to fetch the resource.
The scheme may affect how the rest of the URI is structured and interpreted.
