Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who invented Turing machine?1936
2. What is the theoretical power?Turing complete; capable of simulating any algorithm
3. What is the scientists involved?Alan Turing (inventor), Alonzo Church (coined the term)
4. How does a Turing machine read and write on its tape?The machine's head looks at the symbol in the current cell, then uses a table of rules to decide which symbol to write, whether to move left or right, and which state to enter next.
5. Why is the tape of a Turing machine considered infinite?The tape is infinite so the machine has no memory limits; this lets it simulate any computer algorithm without running out of space.

Infinite Tape: A theoretical memory component without physical limits, allowing for unlimited data storage.
Transition Function: A set of rules that dictates the machine's behavior based on its current state and the symbol it reads.
Halting Problem: The problem of determining whether an arbitrary program will eventually stop or run forever.
Computability Theory: The branch of computer science that studies which problems can be solved by algorithms.
