The computer does not work in our language. So the programme is to put in its own language. The output prints the results with the help of the printing machine. Its signal goes to the memory and the Control Unit leads them to the Arithmetic Unit. After finishing its tasks, it sends them to the result output. Thus result is emitted by computer.
