When answering this question, you can compare online and face-to-face communication from several aspects. For example, online communication is often more convenient and can happen anytime, anywhere, but it may lack the personal touch and non-verbal cues like body language and facial expressions. Face-to-face communication, on the other hand, allows for more direct interaction and can help build stronger relationships, but it might be less convenient due to time and location limitations. You can also mention that misunderstandings can happen more easily online because tone and emotions are harder to convey. Giving examples from daily life can make your answer more vivid.
