Oracle

An oracle is a kind of computer that can answer questions in a way that is very accurate and reliable. It is like a super smart person who can think very quickly. It is used to help people make decisions quickly and accurately. For example, a business might use an oracle to make decisions about buying or selling stock. Or a hospital might use an oracle to help doctors decide which treatments will be most effective for their patients.
