Two types of computers based on internal signaling are analog computers and digital computer. An analog computer represents quantities by physical analogies. It represents physical quantities, such as distance, velocity, acceleration, temperature, pressure, or angular position, force etc, by mechanical or electrical parameters.
An automobile speedometer is an example of an analog-computing device. It converts the rotational rate of the drive shaft of an automobile into the numerical value of the speed of the vehicle, similarly, a thermometer functions as an analog device by converting the movement of a column of a column of mercury into a temperature reading.
Analog computers are ideal in situations where data can be accepted directly from measuring instruments. The ability to collecat data at high speeds and to process data at equally high speeds, makes analog computers uniquely suited to controlling processes of oil refineries, steel mills, weapon systems and similar other operations.
An analog computer does not require any storage capability. The out from an analog computer is generally in the form of readings on a dial or a graph plotted on paper.
Analog computers were in use before the intention of the digital computers. There are far more digital computers in use today than analog computers. This book concentrates on digital computers.
