What does URL stand for and what is it used for?

• A. A password management protocol.
• B. A file extension.
• C. Stands for "Uniform Resource Locator." It is the address of a specific Web site or file on the Internet.
• D. A type of security certificate.

Answer: (C)

A URL is the address your browser uses to reach a resource on the Internet. It stands for Uniform Resource Locator, and it tells the browser where to find a specific web page or file and how to retrieve it. A URL typically includes the protocol (such as http or https), the domain name (like www.example.com), and often a path to a particular file (such as /pages/about.html). The purpose is to locate and fetch the resource so you can view or download it, making navigation across the web possible. For example, https://www.openai.com/help shows a secure path to a web page on OpenAI’s site. The other options describe different concepts: a password management protocol relates to handling passwords, a file extension labels a file type, and a security certificate is a credential that helps establish trust in a secure connection.
