Episodic memory is the storage, retrieval

Semantic memory is the storage, retrieval and use
of general information about the world.
Memory: short and long term components
Short term memory is that information at
the conscious level.
STM is limited and stored only briefly
Long term memory is that information stored
over extended periods of time.
