c. because computers are part of a network, everyone has access to the administrator account
Explanation: The statement "because computers are part of a network, everyone has access to the administrator account" is not true. Access to the administrator account should be restricted and limited to only those individuals who require it for specific administrative tasks. The administrator account typically has elevated privileges, allowing the user to make significant changes to the system. Allowing everyone on the network to have access to the administrator account would pose a serious security risk, as it could lead to unauthorized and potentially harmful actions on the network or system. In a secure environment, access to administrator accounts is tightly controlled to prevent misuse and protect the integrity of the network.
