Functions and Features of Analog Data and Digital Data?
Data can be analog or digital. Analog data mean information that is continues.
Analog data, such as the sound made by human voice, take n continues values.
When someone speaks, an analog wave is created in the air. This can be took by a microphone and converted to an analog signal or sampled and converted to a digital signal.
Digital data take on discrete values. For examples, data are kept in computer memory in the form of 0s and 1s. They can be converted to a digital signal or modulated into an analog signal for transmission across a medium.
