Domains, DNS (Domain Name Service), and hosting are the backbone of everything you see and do on the internet. Without these there is nothing. We explain what each of these do, in simple terms.
Your domain name is how you're identified on the internet. Examples include apple.com and netflix.com.
Domain names are purchased and periodically renewed (typically every year) via a registrar.
DNS (domain name service) is like your lisitng in a phone book, which lists your name, then shows your phone number and address.
DNS is the same for your domain. It tells computers where your emails and website can be found.
Hosting is like your actual phone number or your physical house. This is where telephone calls go to and a map will take you.
There are several types of hosting, but email and web site hosting are the two most common types.
