A domain extension or top-level domain (TLD) is the part of a web address that comes after the domain name, such as ".com", ".org", ".net", or ".edu".
These domain extensions are important because they help identify the purpose and origin of a website. For example, ".com" is typically used for commercial websites, ".org" for non-profit organizations, ".net" for networking technologies, and ".edu" for educational institutions.
There are also country-specific domain extensions, such as ".uk" for the United Kingdom, ".ca" for Canada, and ".au" for Australia.
The Internet Corporation for Assigned Names and Numbers (ICANN) is responsible for managing and overseeing the domain name system, including the assignment of domain extensions. They regularly introduce new TLDs, such as ".blog", ".app", and ".shop", to provide more options for website owners to choose from.
