The term intelligence has been used in a variety of ways, including higher-level abilities (such as abstract reasoning, mental representation, problem-solving, and decision-making), the capacity to learn, emotional awareness, creativity, and the ability to adapt to the demands of the environment.

Intelligence has been studied in humans for years; however, there is controversy about whether non-human creatures and plants have IQ (Intelligence Quotient- numeric representation of one’s reasoning ability). Logic, learning, emotional knowledge, IQ, critical thinking, and creativity are some of the terms that have been used to describe it. As this varies according to an individual’s thinking and efforts, there are various perspectives on measuring this. It is currently known as artificial intelligence because it is found in machines (AI).

The ability to react rapidly to a situation is what intelligence is all about. It can be found in most computer systems that employ various programs or hardware. Intelligence is ideally a combination of cognitive and mental processes, not just one of them. The most prominent theories of the last century include General, Primary Mental Abilities, the Theory of Multiple Intelligence, and the Triarchic Theory of Intelligence.
