A DAC stands for Digital-to-Analog Converter. It's a device that takes a digital signal (usually a series of binary numbers, like 0s and 1s) and converts it into an analog signal.
Digital signals are essentially data that can only have two states, such as "on" or "off" (represented by 1s and 0s). But in the real world, many devices (like speakers, televisions, or even some sensors) work with analog signals, which are continuous, not just on or off.
For example:
So, the DAC bridges the gap between the digital world of computers and the analog world we interact with.

For example:
- When you play music from your phone, the audio file is in a digital format (like MP3). The phone needs a DAC to convert that digital music into an analog signal that can drive speakers, creating sound waves you can hear.
