Describe how bit patterns may represent other forms of data, including graphics and sound. Bit patterns can be used to store information about other forms of data, for example images can be stored using the images height and width in pixels with the colour depth and sound can be stored as digital samples of the original sound. Understand the difference between analogue and digital data. Analogue data is a continuous wave recorded in its original form, when analogue waveforms are sampled at inte...
