Cyber ethics refers to the ethics applied to online behavior. Acceptable behavior online is similar to acceptable behavior offline - one should not use rude language, bully others, plagiarize content, or break into other computers. Some examples of unethical cyber behavior include illegally copying software, interfering with or snooping on others' computers, causing harm to others, or using computer resources without authorization. Following cyber ethics rules is important to promote respect between users and avoid misunderstandings online.
