Data is represented in binary form in the computer.
The reasons why binary is used to represent data in computers:
1. Easy to implement in the circuit: When the computer is working, the circuit notifies the electricity to work, so each output terminal has a voltage. The voltage level is converted into binary through analog-to-digital conversion: high level is represented by 1, and low level is represented by 0.
2. Convenient for addition, subtraction and counting coding. Easy to convert, binary and decimal numbers are easy to convert to each other.
3. Convenient for logical judgment (yes or no). Suitable for logical operations: Logical algebra is the theoretical basis for logical operations. Binary has only two digits, which coincides with "true" and "false" in logical algebra. The two binary numbers correspond to "True" and "False" in logical propositions, or "Yes" and "No".
