  1. Input devices accept data in a form that the computer can use; they then send the data to the processing unit.
  2. The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want.

How do computers manipulate data?

Data processing, manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.
