If the internal structure of the computer is 8-bit, then all eight bits of the data element are transferred between main memory and the central processing unit simultaneously on 8 separate connections. Signals Information can be in the form of voice, data, pictures, etc. To be transmitted, information must be transformed into electromagnetic signals. Both data and the signals that represent them can take either analog or digital form. Analog signals are continuous.
Digital information is discrete.
This signal is represented as a sine wave. It is a simple oscillating curve and its changes over the course of a cycle is smooth and consistent. These are signals that are not sine waves. These are irregular and inconsistent signals. The distance or height of a sound wave is called amplitude .
