Question

Which of the following refers to a web address which uniquely identifies an object over the internet?

  1. A. DNS
  2. B. URL (Correct answer)
  3. C. HOST
  4. D. IP Address

Correct Answer

Option B — URL

Detailed Solution & Explanation

A URL (Uniform Resource Locator) is a web address that uniquely identifies a specific resource (webpage, file, image, video) on the internet. It specifies the protocol (http/https), domain name, and path to the resource (e.g., https://www.example.com/page/article). A DNS (Domain Name System) translates domain names into IP addresses; a HOST is a computer on a network; an IP address identifies a device on a network -- but only a URL specifically and uniquely identifies an object/resource accessible over the internet.
