In computer terms, an avatar is a digital representation of a user, appearing as a 2D graphic or 3D model in online communities, games, and virtual worlds, or even a text-based representation. Users select or create these personalized graphics to represent themselves, allowing for self-expression and interaction within digital environments, functioning as a user's persona or digital identity.
