This is similar to using an address to find a local business or someone’s house. You type the address in on your phone, and you will be directed to the exact location you are looking for. The same thing is true with a domain name. This refers to a unique address that will direct a user over to the right website. People would be unable to locate your website without it. For example, for the website thed3.com, the exact URL is http://www.thed3.com. A majority of individuals tend to use the URL and domain name interchangeably, however, the domain name is actually the part the comes after the www. in the URL.
