Turing Machines vs V Neumann architectures

Turing machines / V Neumann architectures

A few weeks ago we saw videos in class and searched for information about Turing machines and the V Neumann architecture. In this post we are going to see the definitions of Turing machines and V Neumann architectures.

A Turing machine is an idealised computing device consisting of a read/write head (or 'scanner') with a paper tape passing through it. The tape is divided into squares, each square bearing a single symbol--'0' or '1', for example. This tape is the machine's general purpose storage medium, serving both as the vehicle for input and output and as a working memory for storing the results of intermediate steps of the computation.

The von Neumann architecture is a design model for a stored-program digital computer that uses a processing unit and a single separate storage structure to hold both instructions and data. It is named after mathematician and early computer scientist John von Neumann.
