On the internet, a computer is identified by its IP (Internet Protocol) address, which is a unique numerical identifier assigned to each device connected to the internet. However, as IP addresses can be difficult for humans to remember and use, domain names were created to provide a more user-friendly way of accessing resources on the internet. Computers can be known on the internet by their domain names, which are human-readable names assigned to specific IP addresses. For example, the domain name 'google.com' is associated with the IP address '172.217.168.78'.
