Analog computers are able to deal with continuously varying inputs for complex phenomena such as voltage changes and temperature fluctuations. Digital computers must have their inputs reduced to a simple binary language in order to accurately model the world.an analog computer is the speed at which it can process data, although it is only capable of handling several digits or packets of data at a time. A digital computer has the ability to solve an innumerable amount of equations, but it is very slow in processing them.
