Question

A ___________ is a multi tape turing machine whose input tape is read only.

(a) Counter Machine

(b) Multi-stack

(c) Alternating Turing machine

(d) None of the mentioned

I had been asked this question during an internship interview.

I'd like to ask this question from Multistack Machines, Counter Machines topic in section Introduction to Turing Machines of Automata Theory

Answer 1

Right answer is (a) Counter Machine

Best explanation: Counter machines are offline(a multitape turing machine whose input is read only) whose storage tapes are semi-infinite and whose tape symbols contains only two symbols Z and a blank symbol B.
