What is a domain name and extension?

Every domain consists of a name and an extension.

In the example “mydomain.com”,

• “mydomain” is the domain name, and
• “.com” is the extension.

The domain name precedes the extension and it’s the part of the domain that makes a website unique, and, by analogy, a company, an individual, a project, etc.
A simple example would be “mydataknox” as our domain name.
Domain extensions are related to countries, business operations, activities, etc.
Am example of a country-related extension would be “.hr”, which signifies that the domain is related to Croatia. Some examples of business extensions are “.biz”, “.org” and “.com”.
Apart from the previously mentioned extensions, there are many others that cover a wide variety of areas, from professions and services to hobbies. Some examples of such topical extensions are, among others, “.apartments”, “.fitness”, “.pizza”, and “.news”.
