What is the Turing Test? What does it determine about a machine?

The Turing Test was proposed by Alan Turing in 1950. In this test, an evaluator has a conversation with a human and a machine simultaneously and checks the responses given by both.

It determines the intelligence of a machine. If the evaluator finds no difference between the responses generated by the human and the machine, then the machine is considered to have passed the Turing Test.
