Knowledge can be defined as the body of facts and principles accumulated by humankind or the act, fact, or state of knowing. The meaning of knowledge is closely related to the meaning of intelligence. Intelligence requires the possession of and access to knowledge. In biological organisms, knowledge is likely stored as complex structures of interconnected neurons. In computers, knowledge is stored as symbolic structures, in the form of collections of magnetic spots and voltage states. Knowledge external to a computer or a human is represented in the form of written language. For example, Ron is short, Rocky loves Rima, etc.
