Social media allows individuals to connect, share content, and engage in social interactions online through tools and services. It provides places for self-expression to meet and share information. The main purposes of social media include checking Facebook/Twitter, finding research information, communicating via email, downloading content, listening to music, shopping online, chatting, and more. While social media has benefits like connecting people, it also has some negatives such as potential addiction, reduced learning, wasted time, and decreased real human contact.
