Domains

A domain, also known as a Domain Name System (DNS), is a key component of the internet that translates human-friendly website names, like "example.com," into the numerical IP addresses used by computers to locate websites. The DNS acts like an address book for the internet, enabling users to access websites without needing to remember complex sequences of numbers. It ensures a smooth browsing experience by automatically linking the domain name typed into a browser to the appropriate server hosting the website.

The DNS hierarchy is structured into various levels, including top-level domains (TLDs) like ".com" or ".org" and second-level domains, which represent the unique website name chosen by the owner. Domain registrars allow individuals and businesses to register domain names, providing them with a unique online identity. This system is essential for organizing and maintaining the vast number of websites and online services, ensuring that each can be quickly and accurately accessed by users worldwide.
