DNS stands for Domain Name System. It is a system that translates domain names to IP addresses. It is like a phone book for the internet. When you type a domain name in your browser, the browser looks up the IP address of the domain name using DNS.
If you're really interested in learning more about how DNS works, I highly recommend mess with dns, a lovely interactive tutorial that explains how DNS works.
If you're more just interested in how we use DNS, I suggest our guides on sending from a custom domain and hosting on a custom domain.
