Machine
A machine is a device with several parts that work together to perform a task. A machine can augment or replace the efforts required by an animal or human to make it easier to complete a task. For example, a car is a complex machine that transports humans and other things.
Early computing started with adding machines and counting machines, which were machines designed to tabulate logarithms and other functions. For example, Charles Babbage created the difference engine, an advanced counting machine also known as a mechanical calculator. The picture shows the analytical engine, one of Babbage's later machines.
