What is avatar in Second Life?

An avatar is a digital representation of a user in a virtual world like Second Life. In Second Life, each user creates their own unique avatar, choosing their appearance, clothing, and other features. Avatars allow users to interact with each other, explore the virtual world, and participate in various activities. They can be customised in a variety of ways, including appearance, clothing, animations, and accessories. Avatars can also be used to express oneself creatively, as users can design their own unique looks and styles. Additionally, some users create and sell custom skins, clothing, and accessories for avatars within the Second Life marketplace.
