名词 Noun
- (computing theory) An abstract computing machine that has a finite number of possible internal states and operates on an infinite memory tape by first reading a symbol from a cell in the tape, and then, deterministically, based on that symbol and the machine’s state, writing a symbol in that cell, moving to a neighboring cell, and/or changing state.
