Final answer:
Cognition is an active system that processes information received from the senses and retrieves it from storage, while memory is the process of encoding, storing, and retrieving information.
Step-by-step explanation:
Cognition is defined as an active system that receives information from the senses, puts it into a usable form, organizes and alters information as it stores it away, and then retrieves the information from storage. It encompasses processes associated with perception, knowledge, problem-solving, judgment, language, and memory. Memory, on the other hand, is the set of processes used to encode, store, and retrieve information over different periods of time.
