Memory
Memory is the mental capacity to store, retain, and recall information and experiences, serving as the foundation for learning, identity, and decision-making in humans and animals. In modern contexts, it also refers to digital storage devices in computers that temporarily hold data for quick access, highlighting its evolution from a biological wonder to a technological essential that powers everything from smartphones to AI systems.
Did you know?
Did you know that the human brain's memory capacity is estimated to be around 2.5 petabytes—enough to store about three million hours of TV shows—yet it operates with remarkable efficiency using just 20 watts of power, similar to a dim light bulb? This makes our biological memory far more energy-efficient than the most advanced supercomputers, which require massive energy to achieve comparable storage and processing.
