What component of the analytical engine performed calculations?

The component of the analytical engine that performed calculations is known as the "Mill." The Mill is analogous to the modern CPU (Central Processing Unit) in that it is responsible for executing mathematical operations and processing data. It is where arithmetic and logical operations occur, allowing the machine to perform tasks such as addition, subtraction, multiplication, and division.

In contrast, the Store component serves the purpose of holding data and intermediate results during computations, rather than performing the calculations itself. The Input Unit is responsible for receiving data from external sources, while the Output Unit displays or outputs the results of computations. Each of these other components has a distinct function that works in conjunction with the Mill but does not involve performing calculations directly. This differentiation highlights the unique role of the Mill in the analytical engine's architecture.
