The Correct answer is Path.

Key Points

• URL:
  • ​URL, or Uniform Resource Locator, serves as the address for a specific resource on the web.
  • Each valid URL ideally directs to a unique resource, such as an HTML page, CSS document, or image.
  • However, exceptions exist, often when a URL points to a non-existent or relocated resource.
  • The responsibility for managing both the resource and its associated URL lies with the owner of the web server.
  • URL Structure:
    • Scheme:
      • The initial segment of the URL is the scheme, specifying the protocol the browser should employ to request the resource.
      • Typically, for websites, the protocol is either HTTPS or HTTP (its unsecured counterpart).
      • While addressing web pages necessitates one of these two, browsers are also adept at managing other schemes like mailto: (for opening a mail client).

• Authority:
  • ​Following the scheme is the authority, set apart from the scheme by the pattern:/.
  • When present, the authority encompasses both the domain (e.g., www.example.com) and the port (80), separated by a colon:
  • The domain specifies the requested Web server, typically denoted by a domain name, though an IP address may be used (though this is uncommon due to its inconvenience).
  • The port designates the technical "gate" utilized to access resources on the web server.
  • It is usually excluded if the web server uses the standard ports of the HTTP protocol (80 for HTTP and 443 for HTTPS) for resource access.
  • Otherwise, its inclusion is obligatory.

• Path and resources:
  • The path indicates the file or resource location that the user intends to access.
  • it indicates the specific web page or resource 

​

• ​​​Parameters:
  • ​Parameters in a URL represent the values queried during a search.
  • These parameters can encompass various types of data, such as numbers, encrypted values, search terms, or other information present on the website.
  • Each URL parameter consists of a key and a value, connected by an equal sign (=).
  • It is possible for a URL to include multiple parameters, and these are typically separated by an ampersand (&).

• Anchor:
  • An anchor serves as a kind of "bookmark" within the resource, instructing the browser to display the content situated at that specific location.
  • In an HTML document, for instance, the browser will scroll to the position where the anchor is designated.
  • In the case of a video or audio document, the browser will attempt to navigate to the time corresponding to the anchor.
  • Importantly, the segment following the #, commonly referred to as the fragment identifier, is not transmitted to the server along with the request.

The Correct answer is Kevin Ashton.

Key Points​

• Internet of Things-
