The "brain" of the computer is called a processor and is built from units that know how to calculate simple things and are connected to each other by wires that transfer information, similar to trains that carry freight between different points. On the other hand, there are potential "brains," which are a system of tracks and general units for which directions and actions can be chosen. Also, there is a potential "brain," which we develop, which changes in a certain way while working.

We will understand the need for each of these types. Why does a processor need to be constantly changing, and what is a processor at all?
