In computing, an avatar (also known as a profile picture or userpic) is a graphical representation of a user or the user’s character or persona. It may take either a two-dimensional form as an icon in Internet forums and other online communities or a three-dimensional form, as in games or virtual worlds.
An avatar (Sanskrit: अवतार, IAST: avatāra; Sanskrit pronunciation: [ɐʋɐtaːrɐ]), a concept in Hinduism that means “descent”, is the material appearance or incarnation of a deity on earth. … Theologically, the term is most often associated with the Hindu god Vishnu, though the idea has been applied to other deities.
Out of these 24 avatars, 10 avatars, called as Dashavatar, are considered to be the main incarnations of Vishnu. This is Matsya avatar, Kurma avatar, Varaha avatar, Narasimha avatar, Vamana avatar, Parashuram avatar, Rama avatar, Krishna avatar, Buddha avatar and Kalki avatar.
