Binary is a number system widely used in computing technology. Binary data is a number represented by two numbers: 0 and 1. Its cardinality is 2, the carry rule is "every two into one", and the borrow rule is "borrow one when two".
Binary numbers are the carry system of every 2 bits, and 0 and 1 are the basic operators; the basis of computer operation is binary. The basis of computer is binary. The common base in early design is decimal (because we have ten fingers, decimal is a more reasonable choice. Fingers can represent ten numbers. The concept of 0 did not appear until a long time later, so it is 1-10 rather than 0-9).
After the emergence of electronic computers, the use of electronic tubes to represent ten states was too complex, so there were only two basic states in all electronic computers, on and off. In other words, the two states of the electron tube determine that the electronic computer based on the electron tube uses binary to represent numbers and data.
