A domain represents the unique name assigned to an organization or individual on the Internet. For instance, we are all familiar with names such as google.com, microsoft.com, and so on. A particular name (domain) may only be owned by one person or company. To use an analogy, a domain represents your "street address" where you live on the Internet. It uniquely identifies where you can be found. Having a straight-forward, easy to remember domain is crucial to your business success.

The domain name is comprised of several parts. The last part of the domain (e.g., .com) is referred to as the top-level domain (TLD). In theory, the TLD represents a type of entity. For instance, .com stands for "commercial". It was originally meant to be for commercial enterprises (business), but that has become something of a misnomer as even people with personal websites use the .com TLD.
