Input and Output Devices and their relationship with Human Body Parts

The Human body is the entire structure of the human organism that consists of parts that work together so that a human being can perform tasks. Each part has its own function and the absence or malfunction of a part can cause certain problems to the entire structure. Meanwhile, the computer also has input and output devices that function like that of the human body. These are some of them:

Computer Parts - Body Parts

1. CPU- brain
The Human brain receives the data from the nervous system, processes those signals and makes decisions about them and then sends them back to the nervous system again.In the same way, the CPU converts user typed commands into machine language which are sent to concerned parts for decision making and then sent back to the processor to convert them into a user language again.

2.Scanner- eyes
The eyes detect light and translates an inverse image into the real image. The scanner also translates the pattern of light and dark colors into a digital signal so that a certain image will be
transferred from the paper to the computer.

3. Speakers- mouth
The mouth, like the speakers, is where music and words come out to express ideas and emotions.

4. Microphone- ear
The ear helps the person understand another by detecting sound waves. In the same way, the microphone detects sounds so that the computer can understand and record the voices or sounds spoken by the user.

5. Cradles/DockingStations- nose
Just as the nose smells or detects scent, cradles also detects mobile devices which are inserted to it.

6. Keyboard- hands
The hands transmit signals from its sense of touch to the brain to be processed. The keyboard also transmit data and commands (input) to the CPU.

7. Mouse- finger
Both function as pointers and transmitters of signals or commands so that the body can respond to stimuli and the computer can respond to the user. The mouse assists the keyboard and the
finger assists the hand in doing so.

8. Monitor- face
The face show what the brains tells the person to feel. In the same way, the monitor displays what the CPU has processed.

9. Touch screen-skin
The skin is also as sensitive as the touch screen and it can receive impulses felt by touching. The touch screen also accepts data by touching specific places on the screen.

10. Printer- pore
Just as the pore releases sweat and oil which are products ofcertain body processes, the printer also releases or produces output through printing.
