Analogue and Digital Data

Unit 1 .1 Hardware and Software

• Analog data is continuous and has an infinite number of possible values, while digital data is discrete and has a limited number of possible values

• The main difference between analog and digital data is that analog data is represented by a continuous signal, whereas digital data is represented by a series of discrete values.

• Analog data must be converted to digital format for processing by computers. This is because computers work on digital data, and analog data cannot be directly processed by them.

• An ADC (analog-to-digital converter) is a device that converts analog signals into digital data that can be processed by a computer. It converts continuous analog signals into a finite number of discrete digital values.
