Which memory system is considered to have the largest capacity?

Long-term memory is recognized for having the largest capacity among the different memory systems. It can store an immense amount of information over an extended period, potentially for a lifetime. Unlike short-term memory, which is limited in both duration and capacity (typically holding around 7±2 items for a brief period), long-term memory has no known limits on the amount of information it can retain.

This capacity allows individuals to remember a wide range of information, from personal experiences and learned knowledge to skills and facts. Long-term memory can store information in a more organized manner through processes such as encoding and consolidation, contributing to its vast storage capabilities. Additionally, it can effectively retrieve information when needed, further demonstrating its resilience and scope compared to other memory systems.

In contrast, sensory memory and working memory also have their limitations. Sensory memory captures fleeting impressions of sensory stimuli for a very short time. Working memory refers to the system that temporarily holds and manipulates information for cognitive tasks, but it also has restrictions on both capacity and duration. Therefore, long-term memory stands out as the memory system with the largest capacity.
