<p>In the world of computing, intelligence means 'human-like'. Intelligent systems are designed to behave as much like people would in the same circumstances.</p> <p>Computers are programmed to execute smart algorithms: 'if this, then that.' Computers do this immediately and without question – far better than humans. If you apply an algorithm when programming an aircraft, the program says, 'If the plane is at X altitude and is not in landing or taking off mode, sound a warning.' Apply the same programming to a self-driving car, and the program will instruct the car to do things safely, such as stop when there is a red light. The programming team have time to figure out the best course of action, and program the machine to make that happen automatically. This is using a computer to be smart.</p>
