Generic top-level domains (gTLDs), which correspond to thematic fields such as .biz for “business”, .name for private individuals or .pro for professional categories.
Sponsored top-level domains , which must comply with the restrictions imposed by their sponsors, such as .gov for government authorities, .aero for the aviation industry, or .jobs for company job postings.
A second-level domain (SLD) is the name you choose to associate with your top-level domain.
Be careful, do not let the hierarchy of these names fool you. The fact that they are called “second level” does not make them in any way less important than the first level ones, in fact we could say that almost the opposite is true.

Only when you have registered your domain and purchased space from a web hosting provider will your site be online and accessible to everyone.

Registration basically means buying a domain.

Some of the major domain providers are:
Google Domains
