About this resource

Computing — Binary & the Language of Computers, Lesson 6 (final). How sound is a continuous wave, how sampling converts that wave into binary numbers, how sample rate and bit depth affect quality and file size, and how the whole unit ties together — everything a computer stores is ultimately binary.

11 slides.
