separate

Is possible to separate 'CPU' procesor from device motherboard?

You will be able to replace the interface in the future (a better screen , another keyboard, maybe a disk or memory) independently. Improving and optimizing the processor would not require changing external devices. Such a motherboard that includes different hardware could even be produced by others.

ok, You are right.
I think about everything what is not interface. VGA, screen, keyboard etc. I think about separate interface, memory, keyboard to one part and other to other.

Very simple example. Many big computers have memory bank like a memory card or GPU card. Pluging directly to motherboard with interface. You project will be faster when You are put faster memory.

Manufacturing an entire computer is quite difficult. You will find many helpers and speed up the computer if you divide the computer into modules.

One module will deal with the screen and keyboard another with calculations. Then the entry threshold and improving the design, making it faster will become easier for others.
