A domain name is the unique, easy-to-remember address used to identify a website on the internet. It is part of a larger hierarchical naming system, where different parts of the domain provide different levels of identification.
- Subdomain: A subdomain appears before the main domain and is used to create a separate section or service. For example, in
blog.sayzz.com, blog is the subdomain. - Second-Level Domain (SLD): This is the main name that identifies the website or organization. In
sayzz.com, sayzz is the second-level domain. - Top-Level Domain (TLD): This is the extension at the end of the domain name, such as
.com,.org,.net, or.in. Insayzz.com, .com is the top-level domain.
Example: blog.sayzz.com
Here, blog = subdomain, sayzz = second-level domain, and .com = top-level domain.
