(1) From the human perspective, the effectiveness with which a person can analyze a situation or solve a problem.
(2) Information derived for some purpose. See
DOD intelligence glossary.
(3) From the computer perspective, intelligence is having processing capability. In this context, every one of the hundreds of billions of electronic devices in the world that contain a microprocessor are said to be "intelligent." However, the most advanced computer processing today on regular computers (not quantum computers) is artificial intelligence (AI). Ask a chatbot to write a unique essay about anything and that process is called artificial intelligence, yet the microwave oven that heats up your slice of pizza is said to be intelligent and not artificial. An odd twist of terminology. See
smart,
AI and
smart vs. intelligent.
A Twist of Terminology
Because every device with a CPU chip is said to have "intelligence," this coffee maker is intelligent, but the robot that roams the aisles of the supermarket on its own looking for spills and stopping when a person walks by only has "artificial" intelligence.
