Concept:Computer ethics deal with responsible and respectful use of computers, networks, and digital information.
Explanation:Ethical computer practices are behaviours that protect the rights, privacy, and property of others.
Respecting intellectual property means acknowledging and not stealing other people's creative or digital work.
Using polite words when communicating online promotes a safe and respectful digital environment.
However, taking another person's computer or using it without their consent is an invasion of privacy.
Such an action is considered unauthorised access and violates computer ethics.
It is not acceptable even if the user intends no harm.
Permission must always be obtained before using another person's device or data.
Therefore, the option that is not an ethical computer practice is the unauthorised use of someone else's computer.
Answer:D. use of other people’s computer without due permission
