The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, punch cards , and integrated memory. It was the first general-purpose computer concept but unfortunately due to funding issues this project never built while Charles Babbage was alive. In 1910 Henry Babbage, Charles Babbage's youngest son completed a portion of the machine and was able to perform basic calculations.
