What is the term for a computer user's representation of themselves online?

The term for a computer user's representation of themselves online is "Avatar." An avatar serves as a digital persona that users can customize to reflect their identity or interests, often seen in online games, forums, and social media platforms. This representation can range from a simple graphic or image to a more complex 3D model, depending on the platform. Avatars can enhance user interaction by providing a visual identity that others can associate with their online behaviors and communications.

Profiles, while closely related, refer more broadly to the complete set of information about a user on a particular platform, including personal details, interests, and posts, rather than just the visual representation. Icons are typically small images representing software applications or functionalities, while emoticons are textual expressions used to convey emotions in digital communication.
