What are the concepts of chunking and rehearsal?

Chunking is a cognitive strategy that involves grouping individual pieces of information into larger, more manageable units, making it easier to remember and process data. Rehearsal, on the other hand, is the practice of repeatedly reviewing or practicing information to enhance memory retention. Together, these techniques help improve short-term memory and facilitate the transfer of information to long-term memory. They are commonly used in learning and studying to optimize information recall.
