... types of signalling and these can be done in Analogue which means it changes all time in both amplitude and frequency. For example an analogue clock which has its hands moving all the time is changing the time all the time. Whereas with digital signalling which are representations of discrete time signals. For example a digital clock shows the minutes and not the seconds. When the information is being sent over a network when communicating, the information can travel in two forms, these are analogue and digital. The difference between the two is simple that analogue signalling never stops, and the information is being sent continuously, a good example of this signalling is clocks. An analogue clock will never stop, as the second hand is always ticking, therefore one can record an accurate reading of the time to the second, or even millisecond. For example, 1 hour 15 minutes and 24 seconds. ...
