1. What is digital recording?Digital recording turns sounds and pictures into numbers that a computer can store and play back. It lets us keep music, movies, and videos in a very clear, digital form.
2. How does an analog‑to‑digital converter (ADC) work?An ADC samples a sound or image at regular intervals and turns each sample into a specific number. These numbers are stored so the computer can later recreate the original.

Analog-to-Digital Converter (ADC): A device that transforms a continuous analog signal into a sequence of discrete digital values.
Digital-to-Analog Converter (DAC): A device that converts a digital signal back into a continuous analog signal.
Sampling Rate: The frequency at which an analog signal is sampled to create digital data, measured in Hertz (Hz) or kilohertz (kHz).
Bit Depth: The number of bits used to represent each sample, determining the resolution and dynamic range of the digital signal.
