Detailed explanation-1: -Continuous and varying in strength and/or quality. An analog signal is a continuous electrical signal with such variation. The main highway-including gateways, routers, and other communications equipment-that connects all computer networks in an organization.
Detailed explanation-2: -A continuous signal cannot be stored, or processed, in a computer since it would require infinite data. Analog signals must be discretized (digitized) to produce a finite set of numbers for computer use. When analog signals are brought into a computer, they must be made discrete (finite and countable).
Detailed explanation-3: -Analog data is not discrete, but rather is of a continuous nature. Examples of such data are pressure, temperature, voltage, speed and weight. An analog computer makes use of continuous values and not discrete values. Because of this, processes with an analog computer cannot be repeated for exact equivalent results.
