The concept of input and output is used as a tool for thinking about processes.

What happens in-between input and output?

Computer programs take input from peripherals (keyboard, mouse, etc) and files. Then manipulate that input to output information (to the monitor) or instructions (to another program or machine).

To what other processes could the idea of input and output be used?

How about in a biological sense? Could you treat incoming stimuli (such as vision and audition) as input and outgoing actions (such as movement and speaking) as output?

Do the above examples of the application of input and output hint at a similarity between computers and humans? If so, then does that mean that both the CPU (central processing unit) and the CNS (central nervous system) serve the same purpose in a way?
