What is 01

01 refers to the computer 01 code, which is essentially binary. The basic working state of the computer processor is controlled by the on and off of the circuit, which corresponds to the binary 0 and 1. Binary There are only 0 and 1, which is easier for the machine to implement.

Computer 01 code is essentially binary. The basic working state of the computer processor is controlled by the turning on and off of the circuit, which is exactly the same as the binary 0 Corresponding to 1

Binary only has 0 and 1, which is easy to implement on the machine. For example, power on represents 1, and power off represents 0.

The reasons for using binary are as follows:

(1) Binary numbers are the easiest to implement physically. For example, you can use only high and low levels to represent "1" and "0", or you can use the presence or absence of pulses or the positive and negative polarities of pulses to represent them.

(2) The coding, counting, addition and subtraction rules of binary numbers used to represent binary numbers are simple.

(3) The two symbols "1" and "0" of the binary number exactly correspond to the two values ​​​​of the logical proposition "yes" and "no" or "true" and "false", as Computers provide convenient conditions for realizing logical operations and logical judgments in programs.
