what is memory? memory and its types

There are several different types of memory in the human brain. These include:

Sensory memory: Sensory memory is a very brief (less than a second) type of memory that stores information from our senses, such as what we see, hear, touch, taste, and smell.

Short-term memory: Short-term memory, also known as working memory, is a type of memory that holds information for a short period of time (up to about 30 seconds) while we are actively using it.

Long-term memory: Long-term memory is a type of memory that stores information over a longer period of time, often for an indefinite period. There are two main types of long-term memory: explicit and implicit.

Explicit memory is conscious memory, which includes things that we can deliberately remember, such as facts, events, and personal experiences.

Implicit memory is unconscious memory, which includes things that we can't consciously remember but that influence our behavior and habits. This includes things like muscle memory (e.g. how to ride a bike) and classical conditioning (e.g. a fear of a specific stimulus).

Episodic memory: Episodic memory is a type of explicit memory that stores information about personal experiences and events. It allows us to remember specific events that have happened to us, such as our first day of school or our wedding day.

Semantic memory: Semantic memory is a type of explicit memory that stores general knowledge and facts. It allows us to remember things like the capital of France or the formula for water.

It's important to note that memory is a complex process, and these categories are not mutually exclusive. For example, a specific event from our past might be stored in both episodic and semantic memory
