In the context of Turing machines, the head is a crucial component responsible for reading and writing symbols on the tape, as well as moving left or right across the tape. The head’s ability to access and manipulate the tape is essential for the functioning of the Turing machine, as it directly interacts with the data being processed. The head operates based on the current state of the machine and the symbol it reads, influencing how the Turing machine transitions between states and performs computations.
congrats on reading the definition of Head. now let's actually learn it.
