Answer:
Boolean
Explanation:
Boolean is one of the primitive data types that will only hold either true or false value. This data type is commonly used in a variable that will track a status with only two possible outcomes.
For example, the<em> ParticipantPD</em> field is to track the payment status (paid or unpaid) of a participant. So, declare the<em> ParticipantPD</em> field as boolean data type will meet its purpose.
boolean ParticipantPD = true;
or
boolean ParticipantPD = false;
Answer:
I would reset the Domain Name System (DNS)
Explanation:
One factor that could lead to the "Site Cannot Be Reached" error is DNS "poisoning". Another is invalid DNS cache. Both can be caused by an attack on the system by people trying to spoof the system. Spoofing ensures that even when the right address is entered, it leads one to another web address.
One way to quickly reset the DNS is to run ipconfig /flushdns
This helps to clear the DNS cache.
Once the DNS cache has been successfully flushed, the system returns a confirmatory message that reads “flushed the DNS resolver cache”.
The systems administrator can now proceed to reconfigure the IP address(es)
