A domain name or hostname is the address of a website that you type in the URL bar of the web browser. Each computer is assigned an IP address (a series of numbers) to identify them on the internet.
Typically, an IP address looks like a long string of numbers: 192.158.1.38.
With a domain name, you don’t need to remember the long strings of numbers. The domain name is the human-readable name of the specific location where a resource is located.
