analog computer
A type of computer that processes continuously variable information. Information is usually first converted into proportional electrical quantities. These are manipulated by amplifiers and other circuits that perform various mathematical operations. In other words, the analog computer solves problems by dealing with quantities (voltages) that are analogous (similar) to the quantities in the problem. Analog computers are time-consuming to set up an operate. Most work once done on analog computers is now carried out on digital computers, which are simpler and quicker to use.
