Digital Footprint, Net Etiquette & Communication Etiquette
The Internet has become an essential part of our daily lives. Every online activity, such as browsing websites, sending emails, posting on social media, shopping online, or watching videos, leaves traces of information. These traces create our Digital Footprint. As responsible digital citizens, we must understand how our online behaviour affects our privacy, reputation, and safety.
Following proper Net Etiquette and Communication Etiquette helps create a safe, respectful, and positive online environment.
