A domain name is a unique identifier for a website on the internet. It's what you type into a web browser's address bar to find a specific site, such as "google.com" or "wikipedia.org". Domain names are made up of a second-level domain, like "google" or "wikipedia", and a top-level domain, like ".com" or ".org". The top-level domain often indicates the purpose or location of the website, for example, ".com" is commonly used for commercial entities, ".org" for organizations, and country-code top-level domains (ccTLDs) like ".fi" or ".uk" signify a specific country.

Domain names are hierarchical and are organized in a system called the Domain Name System (DNS). DNS acts like a phonebook for the internet, translating human-readable domain names into machine-readable IP addresses (e.g., 192.168.1.1). This translation makes it easier for users to navigate the web without needing to remember complex numerical IP addresses.

Registering a domain name involves choosing a registrar, which is a company accredited to sell domain names. The registration process typically involves searching for an available domain name and then paying an annual fee to secure its use. Domain names are essential for establishing an online presence, branding, and directing internet traffic to a specific website or online service. They are a fundamental component of the internet's infrastructure.
