What is the role of Domain Name Service (DNS)?

The function of Domain Name Service (DNS) is to translate user-friendly domain names, such as www.example.com, into the numerical IP addresses that devices use to communicate with each other over a network. This translation process is essential because it allows users to access websites and services using easily memorable names instead of having to remember long strings of numbers.

When a user types a domain name into a web browser, the DNS servers query databases to find the corresponding IP address and then direct the request to the appropriate server. This process enables the seamless navigation of the internet by mapping human-friendly domain names to machine-readable IP addresses.

Understanding the DNS's crucial role enhances knowledge about networking, as it demonstrates how domain names and IP addresses work together to facilitate internet communication and accessibility.
