The id works according to the pleasure principal, it seeks instant gratification to its desires. It is a completely unconcious part of the mind and thus continues to function even when we are asleep. The id is the part of the mind that is responsible for primative desires such as hunger. In his later works Freud also mentions a 'cultural super-ego' which is responsible for influencing the individual's super-ego.

It is responsible for our inner sense of morality and thus develops as we grow up. The super-ego is the part of the mind that acts as our conscience and tries to impose on the rest of the mind the expectations of society. The word ego is taken directly from Latin where it is the nominative of the first person personal pronoun and is translated as 'I myself'. Its task is thus to find a balance between primative drives, morals and reality.ДЄlthough in his early writings Freud equated the ego with the sense of self, he later began to portray it more as a set of psychic functions such as reality-testing, defence, synthesis of information, intellectual functioning, and memory. In Freud's theory, the ego mediates between the id, the super-ego and the external world. The structural theory divides the mind into three agencies or 'structures': the id, the ego, and the super-ego.

Most people who identify with the contemporary school of ego psychology place its beginnings with Sigmund Freud's 1923 book The Ego and the Id, in which Freud introduced what would later come to be called the structural theory of psychoanalysis. The Structural/Topographical Model of the Mind as an Iceberg. The id contains 'primitive desires' (hunger, rage and sex), the super-ego contains internalized norms, morality and taboos, and the ego mediates between the two and may include or give rise to the sense of self. The ego, super-ego, and id are the divisions of the psyche according to the psychoanalytic theory developed by Sigmund Freud.
