Computers use a system called binary, which is based on just two values: 1 and 0. These values represent electrical states, like on and off, making them reliable for machines to process.
By combining millions of these signals, computers can represent text, images, sound and instructions. Everything from a simple message to a complex game is built using this system.
At first, binary may seem limited but it becomes extremely powerful when scaled. In many ways, all modern technology runs on this simple foundation.
