Analogue & Digital Data

Analogue Data

Continuous data that varies smoothly over time.

Digital Data

Discrete data represented in binary form (0s and 1s).

Differences between Analogue & Digital Data

Analogue data can have any value within a range, while digital data has a limited set of values. Digital data is less prone to noise and distortion compared to analogue data. Digital data can be easily manipulated, stored, and transmitted by computers.

Converting Analogue to Digital Data

The process of converting analogue data to digital data so it can be processed by a computer. This process is called analogue-to-digital conversion (ADC) and is performed by an analogue-to-digital converter.

Converting Digital to Analogue Data

The process of converting digital data to analogue data so it can be used to control devices. This process is called digital-to-analogue conversion (DAC) and is performed by a digital-to-analogue converter.
