Final answer:
The statement that each domain-based namespace is managed independently is true. Domain administrators are responsible for their own namespaces, configuring subdomains and managing DNS records without influence from other domains, although they are part of the larger DNS infrastructure.
Step-by-step explanation:
True or False: Each domain-based namespace is managed independently. This statement is true. A domain-based namespace in a computing context, such as a DNS (Domain Name System) namespace, is managed on an individual basis. The management of each domain is the responsibility of the domain owner and is typically done in accordance with the rules and policies set by governing bodies such as ICANN (Internet Corporation for Assigned Names and Numbers) for global top-level domains or by internal policies for private networks.
Domain administrators have control over their respective namespaces, allowing them to create, modify, and delete subdomains and manage the DNS records associated with their domains. For instance, the administrator for 'example.com' manages the DNS records for subdomains like 'mail.example.com' and 'www.example.com' independently from other domain namespaces.
It's important to note that while each domain-based namespace is managed independently, they are still part of a larger, interconnected network that relies on global DNS servers for resolution and routing of internet traffic.
