Positions of gears represent numbers Blaise Pascal, Wilhelm Leibniz, Charles Babbage Babbage’s Difference Engine Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. The first difference engine was composed of around 25,000 parts, weighed fifteen tons (13,600 kg), and stood 8 ft (2.4 m) high. Although he received ample funding for the project, it was never completed. (Wikipedia) Augusta Ada, Countess of Lovelace (1815-1852) Mainly known for having written a description of Charles Babbage's early mechanical general-purpose computer, the analytical engine. She is also known as the "____________________________". The computer language Ada, created by the U.S. Defense Department, was named after Ada Lovelace. Early Data Storage Punched cards used in Jacquard Loom (1801) to store patterns for weaving cloth Storage of programs in Babbage’s Analytical Engine Popular through the 1970’s The Jacquard loom was the first machine to use ____________________________to control a sequence of operations. Did not do computation, but important in history of computer science. The ability to change the pattern of the loom's weave by simply changing cards An important conceptual precursor to the development of computer programming.
