A generic top-level domain (gTLD) is an Internet top level domain. You can recognize it at the end of the domain name after the “.” or “dot” (example.com).
The top extensions like .com, .net, .org and .info are available for registration for the general public and organizations.
It can be used for any needs like starting a blog, a professional web page, a personal website, an online portal or a business website.
Some of the extensions are restricted to use of a specific group of people.
