Dictionary of Computers - analogue
analogue
(Of a quantity or device) changing continuously; by contrast, a digital quantity or device varies in series of distinct steps. For example, an analogue clock measures time by means of a continuous movement of hands around a dial, whereas a digital clock measures time with a numerical display that changes in a series of discrete steps.
Most computers are digital devices. Therefore, any signals and data from an analogue device must be passed through a suitable analogue-to-digital converter before they can be received and processed by computer. Similarly, output signals from digital computers must be passed through a digital-to-analogue converter before they can be received by an analogue device.
