Domain

A domain is a human-readable name used to identify a website or online service on the internet.

Instead of entering a numerical IP address, users can access a website through a domain such as example.com. The domain is resolved through the Domain Name System so the browser can locate the correct server.

Also known as: Domain name, website domain.

How Is a Domain Structured?

A domain name is usually made up of multiple levels separated by dots.

For example:

www.example.com

This domain contains several parts:

• Top-Level Domain (TLD): com
• Second-Level Domain: example
• Subdomain: www

Together, these components form the full domain name.
