I was reading about the history of computers where i came by machine code
A Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an ALU operation on a unit of data in a CPU register or memory.
The computer here does logical operations like load or jump steps using the machine code.
From the Wikipedia page a computer is
A general-purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically.
This means from the machine code the computer can perform logical or arithmetic operations, but which principle computers are based on the logical principle or the mathematical principle ?
What can be said also as the natural language of a computer ?
[Edit] both answers solved my problem.
