What does peg system mean in memory?

The peg system is a mnemonic device that helps improve memory retention by associating information with a predefined set of "pegs" or anchors. Each peg is typically a number or a Word that is easy to remember, and it serves as a hook onto which new information can be attached. For instance, the numbers one through ten can be associated with specific objects (e.g., one is a bun, two is a shoe), allowing individuals to visualize and link new items to these familiar pegs. This technique enhances recall by leveraging structured associations.
