Long-term Memory is the capacity to maintain information as little as a few days or as long as decades. It differs structurally and functionally from working memory or short-term memory, which ostensibly stores items for only around 20–30 seconds. However, long-term memory is closely related to short-term memory, as items that are stored for a short time can become long-term through the process of rehearsal and meaningful association.

Example: Do you remember the name of your first grade teacher? The year Columbus discovered America? These are both example for using your long-term memory to retrieve the required information.
