: These take digital data (like an MP3 file) and turn it back into a continuous electrical wave to drive a speaker so you can hear it.
: Information is processed through logic gates (AND, OR, NOT) that perform mathematical operations on bits. Analog and Digital Electronics
: Often more energy-efficient for simple tasks and can have lower latency (delay) than digital counterparts. Digital Electronics: The Logic of Information : These take digital data (like an MP3
