CPU and Turing Machine

1. CPU

1.1. A central processing unit is the electronic circuitry in a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control.

1.2. The computer industry has used the term "central processing unit" at least since the early 1960s

1.3. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit, distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.

2. Turing Machine

2.1. A Turing machine is an abstract machine that manipulates symbols on a strip of tape.

2.2. it is a mathematical model of computation that defines such a device.

2.3. The Turing machine was invented in 1936 by Alan Turing.
