DNS, or the Domain Name System, is a crucial component of the internet that is responsible for converting human-readable domain names into IP addresses, which are the numerical identifiers used by computers to locate and communicate with each other on the internet.
In simple terms, when you enter a website address into your browser, the DNS system is what takes that address (e.g., “www.example.com“) and translates it into the IP address of the server where the website is hosted (e.g., “192.0.2.1”).
The DNS system operates like a global directory of domain names and IP addresses, allowing computers to look up and find the IP addresses of websites and other resources on the internet. This enables you to access websites and other resources by simply entering a domain name, rather than having to remember the IP address of every resource you want to access.
DNS also provides other important functions, such as enabling email delivery, enabling secure web connections (HTTPS), and allowing you to use custom domain names for your website or other online resources.
In short, the DNS system is what makes the internet a more usable and user-friendly place, allowing you to access online resources easily and efficiently. Without DNS, you would have to remember and enter the IP addresses of every website and online resource you wanted to access, making the internet much less accessible and useful.
