Final answer:
The correct term to complete the statement is Invalid. An invalid domain indicates that the computer or DNS does not exist.
Step-by-step explanation:
The correct term to complete the statement is A. Invalid. An invalid domain indicates that the computer or DNS does not exist. When a domain is invalid, it means that the address or hostname cannot be resolved or accessed on the network.
This term is commonly used in the context of computer networking and internet protocols. It is important to ensure that domains are valid in order to establish successful connections and communication between computers and servers.
For example, if you try to access a website by entering an invalid domain name, such as 'www.exampl.com' instead of 'www.example.com', your browser will not be able to resolve the domain and you will see an error message indicating that the website is not found or does not exist.
