An analog computer does not use discrete steps, but smoothly models whatever is being calculated. Most are specialized devices, but the (good old) slide rule was a general purpose analog computer. It's one great advantage is speed, and high speed digital computers have mainly taken over.
It works on a constant supply of varying signals (and not necessarily even electrical). For instance, an automatic transmission in a car is pretty much an analog computer. As the pressure of the pump and the signals on the governor and modulator valve vary, the fluid goes through different valves in the control body and controls which transmission bands are applied at what particular time.
The more sophisticated of the mechanical clocks are also analog computers, as well as the old adding machines. Gears and tumblers had to make up for a lack of circuitry.
it is the letheral way of answering some question.

A light pen is a peripheral input device, used for inputting analog information in a digital format.The "analog" information may be a plan or drawing which needs to be digitized so that it can be manipulated in a computer program.An architect for example may use a pen to copy a set of drawing into he computer so that they can be manipulated in a CAD program.

No. Sound has to be converted from analog to digital for use by a computer, not the other way around. It is converted to analog so amplifiers and other analog equipment can use it and so you can hear it.

it was an astronomical calculator. A form of mechanical analog computer. The nordon bombsight was also a form of mechanical analog computer.

Digital to analog converter.An analog to digital converter and digital to analog converter are present in a computer. they serve this purpose. They are present in the form of ICs inside.
Because I am an analog creature living in an analog world. If I were a computer I would use digital communication. :-/ ?
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
