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.
