A domain name is the information that you enter into a web browser in order to reach a specific website. When you input a URL like www.example.com/index into a web browser, its domain name is example.com. Basically, a domain name is the human-friendly version of an IP address. Businesses vie for easy-to-remember domain names, since they make it easier for people to remember how to find them online. If people had to remember complex IP addresses in order to navigate the Internet, it wouldn't be nearly as useful or enjoyable.
