ABSTRACT
The process of digitally storing moving images and sound begins by converting once analog video and audio signals into a stream of discrete representations of binary numbers corresponding to sampled levels of chroma and luminance (for video) or for audio, correlating the changes in dynamic air pressure, which have already been converted into electrical signals as they were captured by transducers over time. In the digital media world, this string of binary information is represented as data and is often referred to as bits and bytes.
