Social media refers to online platforms and technologies that enable users to create, share, exchange, and interact with content and each other. These platforms facilitate communication and community building through various forms of media, including text, images, videos, and live streams. Social media encompasses a wide range of applications and services, such as social networking sites (like Facebook and LinkedIn), microblogging platforms (like Twitter), media-sharing services (like Instagram and YouTube), and messaging apps (like WhatsApp and Snapchat).

Users can engage with each other by posting updates, commenting, liking, and sharing content, which helps to create a dynamic and participatory online environment. Social media has become a significant influence on communication, marketing, and information dissemination, impacting personal relationships, business strategies, and social movements. It plays a crucial role in shaping public opinion and fostering community engagement while also raising concerns related to privacy, misinformation, and mental health.
