Invention: Analytical Engine 10297676.jpg

Years: 1833-1842

Description:
The Analytical Engine was designed to be programmable, to be able to do any kind of calculation, to be a fully-automatic calculating machine. It was the world's first general-purpose computer.

The Analytical Engine was the first machine designed to use it's own calculations (output) as input for further equations. Babbage adapted the Jacquard loom punched cards to input information and instruction to be performed.

The Analytical Engine was as large as a house, powered by 6 steam engines. The engine consisted of two parts: the mill and the store. Today we would consider the mill to be the CPU and the store would be the RAM.
It was never fully functional, but it was the first design to give us the basics of a computing machine and not just a calculator.
