Brief History of AIAugusta Ada (1815-1852)  work on Charles Babbage’s early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is recognised as the first algorithm intended to be carried out by a machine. Because of this, she is often described as the world's first computer programmer.

Abstraction and quantity of data, information, and knowledge

Data are processed and organized as information. Information is then collected and abstracted as useful

resource (knowledge) for human beings to solve corresponding problems.
