Immunity:  The state of being immune from or insusceptible to a particular disease or the like.  The condition that permits either natural or acquired resistance to disease.  The ability of the cell to react immunologically in the presence of antigen.

Natural Active  Occurs during infection.  It is active because lymphocytes are activated by antigens on pathogen's surface.

Artificial Active  Injecting or taking antigens by mouth.  Takes time for T and B cells to be activated but gives long lasting immunity.

Active Immunity  Memory cells are only produced in active immunity.  Protection for active immunity is permanent whereas in passive immunity it is only temporary.  Antigens are only encountered in active immunity.  Active immunity takes several weeks to become active but passive is immediate

Natural Passive  Mother to child through placenta or milk.

Artificial Passive:  Used during potentially fatal diseases. Provides an instant response but only temporary as antibodies are not the body's own so memory cells are not created. E.g. tetanus - injection of antitoxins given.
