1.1. Is an abstract Mathematical Object
1.2. Describes infinitely operations
2. How does it work ?
2.1. 1. Input: Tape with a code of ones and zeros
2.2. 2. The machine looks at the tape one square at a time. Then follows some rules, transforming that string of ones and zeros into a diferent one.
2.3. 3. Output: Tape with a different code of ones and zeros.
3. Structure
3.1. Tape/Memory
3.1.1. The lenght is how you want it to be
3.1.2. Divide into cells, each one containing ones and zeros
4. Created by Alan Turing
