A domain name is the unique name that identifies an Internet site. For example, www.webbloom.com.
Domain names always have 2 or more parts, separated by dots. The main part (i.e. webbloom) is the most specific and often is a company name or description of the company. The part on the right is the most general and is called a top-level domain, or TLD.
Common TLDs are .com, .net, and .org.
