Lecture 1-2

Analytical engineCharles Babbage was a mathematician, philosopher, inventor and

mechanical engineer who originated the concept of a digital

programmable computer. After the attempt at making the first

difference engine, Babbage worked to design a more complex

machine called the Analytical Engine. A portion of the difference

engine shown in the fig.

The analytical engine is a machine, first proposed by Charles

Babbage in 1837, that is considered to be the concept for the first

general mechanical computer. The design featured an Arithmetic

Logic Unit (ALU) and permitted basic programmatic flow control.

It was programmed using punch cards (inspired by the Jacquard

Loom. It also featured integrated memory. For these reasons,

historians consider it to be the first design concept of a general-

purpose computer.

Unfortunately, because of a lack of funding, the Analytical Engine was never built while

Babbage was alive. It wasn't built until 1910 that Henry Babbage, Charles Babbage's youngest

son, was able to complete a portion of this machine which was able to perform basic

calculations.
