WebA sensing read/write head: this would be able to look at a square on the tape and read its symbol. In response to what was read, the machine could leave the symbol unchanged, or … WebThe tape head has the ability to move to, read, write, and erase any single square and can also change to another internal state at any moment. Any such act is determined by the internal state of the machine and the condition of the scanned square at a given moment.
WebWith this head, the machine can perform three very basic operations: Read the symbol on the square under the head. Edit the symbol by writing a new symbol or erasing it. Move … WebA Turing Machine is a mathematical construct. For the purposes of mathematics, it's a set of rules that you follow. It doesn't get the "instructions" from anywhere, it's defined by the person designing the Turing Machine. A Turing Machine can read what is written where the "read head" is positioned.
