Domain Name System (DNS)

The Domain Name System (DNS) is a critical component of the internet's infrastructure, acting as the internet's phone book by managing the mapping between human-friendly domain names (like www.example.com) and their corresponding IP addresses. DNS allows users to access websites using domain names instead of complex IP addresses, facilitating an easier and more intuitive way of navigating the internet.
