Which term refers to the "address" or URL of a specific website?

The term that refers to the "address" or URL of a specific website is the domain name. A domain name is a human-readable address that allows users to access a website easily instead of needing to remember a more complex numerical representation of the website, known as an IP address. For example, "www.example.com" is a domain name that points to a specific web server hosting the website’s content.

Using a domain name is essential for the usability of the internet since it provides a way for people to find and reach websites using familiar terms rather than a sequence of numbers. This efficiency in navigation has made domain names a fundamental aspect of web development and user experience.

While the other terms are related to internet addressing, they do not serve the same purpose. An IP address is the numerical representation of a device on the internet, a page title pertains to the name of a specific web page usually seen in the browser tab, and a host name is often part of a domain name that identifies a specific machine on a network.
