What does the term URL mean?
Uniform Resource Locator (URL) is a technical term. A URL refers to the network address where a computer resource is located, such as a computer file or a peripheral device (printer, multifunctional device, network drive, etc.). This network can be the Internet, a corporate network (such as an intranet), etc.
In TCP / IP networks, a complete URL has the following structure:
schema: // domain: port / path / resource? query_string # fragment
- The scheme is the protocol. It could be HTTP, HTTPS, FTP etc.
- The domain is the address of the machine: it designates the server that makes the requested document or resource available.
- The port is the logical point at which to connect to the server. (optional)
- The path specifies the location (usually on a file system) where the resource is located, within the server.
- The query string is a set of one or more "question-answer" or "parameter-argument" pairs (such as name = so-and-so, where name can be, for example, a variable, and so-and-so is the value (argument) assigned to name). It is a string sent to the server so that it is possible to filter or even create the resource.
- The fragment is a specific part or position within the resource.
