Computer related contributions

• Designed the first mechanical computer, which he called the "Difference Engine" — a machine that could solve polynomial equations without using multiplication or division. He began developing the machine in 1822, and worked on it for over ten years, but its construction was never completed.
• Invented and developed his Analytical Engine in the late 1830s. Like the Difference Engine, the Analytical Engine was never fully constructed, but its design was highly influential.
• His machine designs were the first to employ several important concepts used in modern computers, including the separation of data and program memory, instruction-based operations, program control using conditional jumps, and a discrete unit for input/output. Because of this, today he is widely considered to be the father of computing.
