Final answer:
Information retrieval is the process of accessing previously learned information, and it can be done through recall, recognition, or relearning.
Step-by-step explanation:
Information retrieval refers to the act of getting information out of memory storage and back into conscious awareness. It is the process of accessing previously learned information. This could be done through recall, recognition, or relearning.
Recall is the ability to access information without cues. For example, remembering your 16th birthday party without any prompts. Recognition is identifying information that you have previously learned after encountering it again. An example would be recognizing your high school classmates in their yearbook photos. Relearning is the process of learning information that you have previously learned. An example would be quickly picking up the Spanish language after not speaking it for many years.
