Web, domains and email
DNS
Abbreviation for Domain Name System
In short and in plain language
The DNS is the address book of the internet. It turns domain names into the addresses of the right servers.
Its records say, for example, where the website is kept. They also say which server takes in email.
When a domain or a website moves, these records are changed.
Definition
The DNS is the directory of the internet that translates domain names into the addresses of the responsible servers. Its records state, for example, where the website is hosted and which server accepts email. When a domain or website moves, these records are switched.
