Learn in the textbookDomain Names, DNS, and How the Web Works
DefinitionA URL is a way of writing where information on the internet, such as a web page, is located.
ExplanationShort for Uniform Resource Locator, it looks like https://www.example.ne.jp/news/top.html. The scheme (スキーム) at the start gives the communication method, the domain name gives the destination, and the path (パス) at the end gives the location on the server. A host name (ホスト名) such as www to the left of the domain name refers to a computer or the like within that domain.
AnalogyLike a slip that reads "Central Library, floor 3, shelf B, fifth book."
Memory hookLocator means something that pins down a place. The L reminds you that a URL points to a location, not to the content.
