What is an important reason for studying Turing machines?.
- A.They provide a formal model of computation and help define what is computable
- B.They are the only machines that can store data on a tape
- C.They are used to replace all high-level programming languages
- D.They guarantee that every possible computation will halt
Model answer
What a good answer should say
- They provide a formal model of computation and help define what is computable
Explanation
Why this works
Turing machines are important because they give a general and formal model of computation. A Universal Turing machine is significant because it can represent and carry out the actions of other Turing machines.
