★ Must-know
📌 A computer obeys literally, follows instructions in order unless told to jump, and never guesses what an unclear instruction means.
📌 An instruction can be carried out only when it has one single definite meaning, so phrases such as “buy some rice” or “charge a fair price” must be made precise before a computer can act on them.
