Computers use a central processing unit (CPU) to process data by interpreting instructions stored in memory. A monitor is only used for displaying data after it has been processed, not for the actual processing itself. Similarly, outputting physical objects (such as printing) and inputting physical objects (such as scanning) are also not part of the data processing process. These actions are considered forms of input and output, not the actual processing of data. Only by interpreting instructions can a computer process data and perform tasks.
