Monotheism
Monotheism is the belief that there is only one God. Monotheism is a characteristic of the Abrahamic religions.
Pantheism
Pantheism generally holds that God and the universe (or reality) are one and the same thing. God in this sense is often not at all conscious. In some pantheistic views, the evolution of life, especially of humanity, represents the universe attempting to become conscious of itself.
Abrahamic monotheism
In Abrahamic religions (Christianity, Judaism, and Islam), God is the creator and supreme master of the universe. In Judaism he is called Yahweh (YHVH) or Elohim (though Judaism teaches against speaking the name of God, so Adonai usually replaces Yahweh, and Hashem usually replaces Elohim). In Islam he is named Allah. All Abrahamic religions are monotheistic.
