Answer:
One remembers general ideas, and the other remembers specific events.
Step-by-step explanation:
Semantic memory falls in the category of explicit memory (or declarative memory). It consists of the general world knowledge a person possesses accumulated through our life experiences.
Episodic memory is the memory of specific event in a person's life.
Let us take an example, from our memories we know what a dog is, this is semantic memory. Now, a person's memory of petting a dog which he/she received on their birthday is an example of episodic memory.
