Interface
= an intermediair which enables 2 systems to communicate with each other
Protocol
= a set of rules or procedures for transmitting data, preexisting agreement as to how the information will be structured and how each side will send and receive it.
Sound
= vibration sound waves travel much like ripples over the water


sound = vibration: we take a container, put some plastic on top and some sugar or coffee, when we hit with a stick on a pan/pot or a trompet, coffee will move

frequency
= vibration per second --> Hertz

The electromagnetic spectrum --> power - telephone - radio/tv - microwave - ir - uv - x rays

  • delta brain waves: 0.5 to 4 Hz
