DIFFERENCES BETWEEN DIGITAL AND ANALOGUE DATA AND COMPUTERS

#	ANALOGUE	DIGITAL
1	analogue data is continuous in nature (continuous data is quantitative data that can be measured. • it has an infinite number of possible values within. a selected range e.g. temperature range.)	digital data is discrete in nature (discrete data is quantitative data that can be counted, Discrete data is based on counts. Only a finite number of values is possible, and the values cannot be subdivided meaningfully.)
2	less accurate	more accurate
3	more affected by other factors	less affected by other factors
4	requires complex programs to run	requires simple programs to run
	Famous examples of analog computers are the Planimeter, the nomogram, operational amplifiers, mechanical integrators, slide rules, tide predictors, electric integrators that solve partial differential equations, electronic machines that solve ordinary differential equations, machines to solve algebraic equations, the Norden bomb sight, and neural networks.	All modern computers, laptops, and calculators are all digital computers.
