Memory is a cognitive ability that enables individuals to store, retain, and recall information. It refers to the process of encoding, storing, and retrieving experiences, facts, and events in our brain. Memory is divided into three main stages: sensory memory, short-term memory, and long-term memory. Sensory memory holds information from our senses briefly. Short-term memory retains information for a short duration, typically up to 30 seconds. Long-term memory is the storage of information over an extended period, allowing us to remember past experiences, knowledge, and skills. Memory plays a crucial role in learning, problem-solving, decision-making, and overall cognitive functioning.
