A second-level domain or SLD is the portion of the domain name that is located immediately to the left of the dot and domain name extension. For example, the SLD in consoleindiainc.com is consoleindiainc.

What is the ‘www’ before my domain name?

The www before your domain name is a subdomain and it is not part of the domain name itself. Therefore, if someone sets the www CNAME record to point to primary A record, the website will resolve both at www.yourdomain.com and yourdomain.com.
