What is DNS Server?

DNS stands for Domain Name System, which is a system that helps to translate domain names into IP addresses. DNS servers store all the domain names and their corresponding IP addresses, which enables the users to access websites using domain names instead of IP addresses.

For example, when you type www.google.com in your web browser, the DNS server will translate this domain name into an IP address that your computer can understand and access the Google webpage.

DNS is an essential component of the internet, and without it, we would have to memorize IP addresses to access websites, which would be very inconvenient.
