The term ".com" refers to a top-level domain (TLD) used in the Domain Name System (DNS) of the Internet. Originally intended for commercial entities, it has become the most popular TLD, representing a wide range of websites, including businesses, blogs, and personal pages. When a user types a web address ending in ".com," their browser connects to the corresponding server to retrieve the website. This domain is managed by the Internet Corporation for Assigned Names and Numbers (ICANN), which oversees domain name registrations and ensures the stability of the Internet's naming system.
