A domain name is used to identify and locate a website on the Internet. It is a unique name that is assigned to a website and is used to access it through a web browser.
When a user types a domain name into the address bar of a web browser, the browser sends a request to a domain name server (DNS) to resolve the domain name to an IP address. The IP address is the unique numerical label assigned to each device connected to a computer network, such as the Internet. Once the domain name is resolved to an IP address, the browser can then connect to the web server associated with that IP address and request the website.
Domain names are also used for email addresses, for example, you can have an email address like "username@example.com" where "example.com" is the domain name used.
Additionally, domain names are also used for various other services like instant messaging, file transfer, and remote access.
In summary, domain names are used as a way to easily remember and access a website or other online resources, without the need to remember a long string of numbers (IP address).
