  1. A digital answering machines convert a caller's message into bytes of data for storage in much the same way that music is stored on a compact disc. When a call comes in to the answering machine, its microcontroller uses an analog-to-digital converter to digitize the caller's voice. It then stores the digitized data on a specific address in the machine's random access memory (RAM). When you want to play the message back, the microcontroller runs the digitized data through a digital-to-analog converter and plays it over the speaker.
