What does "online etiquette" include?

Online etiquette encompasses a variety of behaviors that contribute to respectful and positive interactions in digital environments. The principle of respectful communication is fundamental; it involves treating others with consideration and kindness, akin to how one would communicate in person. This includes being mindful of tone, avoiding aggressive language, and being tolerant of differing viewpoints.

Keeping private information secure is another crucial aspect of online etiquette. This involves understanding the importance of privacy and the responsible handling of sensitive information, both personal and that of others. This not only protects individuals' privacy but also fosters trust in online communications and interactions.

The other options provided do not encapsulate the full scope of online etiquette. For example, using only professional language in all online interactions can be overly rigid, as informal communication is often appropriate in social contexts. Restricting discussions to business-related topics misses the importance of casual conversation that helps in building relationships. Additionally, limiting communication solely to video calls disregards the variety of formats available for interaction, ranging from emails to messaging apps, which can all be used appropriately depending on the context.
