Domain names are the human readable IP addresses of a website. It is interesting to note that domain name can never be more than sixty- three characters(which excludes .com, .org, .net, .edu, etc.)
The domain URL contains the protocol, subdomain and then comes the domain and domain suffix.
Let’s read full meaning of Domain:
https: ( Protocol)
bing.com (domain and domain suffix)
It is the main priority in any URL. It is the name of the website which is bought by the registrars. For example: if a website name is Todays Era, then the domain name can be .todaysera.com. In this, todaysera.com is the root domain of the website.
Subdomains are the third priority of any domain. It is the free distinction given by the internet to every website. It contains the complete website name. as taken earlier, if we take the example of a website called girls nation, then .todaysera.com will be the root domain and www.todaysera.com will be the subdomain.
If you are keeping the domain name as http://todaysera.com then this means that there is no subdomain. The complete URL will be http://www.todaysera.com.
