Which type of memory is characterized as being relatively permanent and limitless?

Long-term memory is characterized as being relatively permanent and limitless because it is designed to store vast amounts of information over extended periods of time, often for years or even a lifetime. This type of memory encompasses various forms, including episodic memory (which pertains to personal experiences), semantic memory (which involves facts and knowledge), and procedural memory (which relates to skills and tasks).

In contrast, short-term memory holds information temporarily, typically for just a few seconds to minutes, and has a limited capacity. Working memory, which is an extension of short-term memory, is actively involved in processing and manipulating information rather than simply storing it. While episodic memory is a specific type of long-term memory focused on personal experiences, it does not encompass the entirety of long-term memory's characteristics. Overall, long-term memory's permanence and capacity set it apart as the most comprehensive form of memory storage.
