Which is the correct sequence according to DNS naming convention?

The correct sequence according to the Domain Name System (DNS) naming convention is as follows:

1. Top-Level Domain (TLD): This is the highest level in the DNS hierarchy and serves as the broad categories of domain names. Examples of TLDs include .com, .org, .net, and .gov.

2. Second-Level Domain (SLD): The SLD comes immediately after the TLD and identifies specific entities, organizations, or websites within the TLD. It typically represents the name of the organization, company, or website using the domain.

3. Subdomain: Subdomains further divide the SL D o r provide additional hierarchical levels within the domain name. Subdomains are commonly used to organize different sections or departments of a website, such as www, mail, blog, etc.

The sequence can be summarized as follows:

. Second-Level Domain . Top-Level Domain

For example:

www.example.com

In this case, "www" is the subdomain, "example" is the Second-Level Domain, and ".com" is the Top-Level Domain.
