	'''Analog''' is a term used in computer-related discussions to describe the lowest ''conceptual'' level at which computer components can be examined. (Obviously, in actuality, all computers are 'analog' at their lowest level, since they are built out of [[electricity\|electrical]] [[circuit]]s.)		'''Analog''' is a term used in computer-related discussions to describe the lowest ''conceptual'' level at which computer components can be examined. (Obviously, in actuality, all computers are 'analog' at their lowest level, since they are built out of [[electricity\|electrical]] [[circuit]]s.)

	~~As such~~, ~~things~~ such as [[voltage]]s, [[current]]s, [[resistor]]s and [[transistor]]s are the ~~concepts~~ used. Note particularly that voltages are not [[binary]], but can take any value ~~(one of the meanings of 'analog')~~; this is important in topics such as [[meta-stability]].		It also has a main meaning of referring to things which have infinitely variable values; i.e. the values have to be measured in [[real number]]s, not [[integer]]s (which is the case with most [[digital]] devices).

			Things such as [[voltage]]s, [[current]]s, [[resistor]]s and [[transistor]]s are both:

			* the elements used at the lowest conceptual level; and
			* things which have infinitely variable values.

			Note particularly that voltages are not [[binary]], but can take any value; this is important in topics such as [[meta-stability]].

	The term (sometimes spelled in the old-fashioned form '''analogue''' in this usage) is also used to name [[computing device]]s, [[analog computer]]s, in which the fundamental, basic data items have infinitely variable values (voltages, currents etc) - i.e. the meaning above - instead of the limited, ''discrete'', values used in [[digital]] computing devices.
