"An analog computer is a computing device that has two distinguishing characteristics: (1) Performs operations in a truly parallel manner. Meaning it can perform many calculations all at the same time. (2) And operates using continuous variables. Meaning it uses numbers that that change not in steps, but change in a smooth continuous manner. By constrast, a digital computer can only perform sequential (one at a time) operations, and operates on discrete (noncontinuous) numbers."
