# Binary

Binary, a system of expressing numbers using only two discrete symbols (typically: 1, and 0), is the system used by modern digital computers for simple numeric quantities. It was Claude Shannon who made the connection between George Boole's work on logical systems based on true and false values and using electronic circuits to implement them as circuitry. Using a binary system makes a physical implementation much simpler than a decimal system such as Charles Babbage's Difference Engine.
