What is the basis of computer operation?

Binary system is a digital system widely used in computing technology (calculator), which was invented by the German master of mathematical philosophy Leibniz in 1679. Binary data are numbers represented by 0 and 1.

Its cardinal number is 2, the carry rule is "every two enters one" and the borrowing rule is "borrowing one as two". At present, the computer system basically adopts binary, and the data is mainly stored in the computer in the form of complement. The binary in the computer is a very tiny switch, where "On" stands for 1 and "Off" stands for 0.

One of the important signs called the third scientific and technological revolution in the 20th century is the invention and application of computers, because digital computers can only recognize and process codes consisting of' 0'. 1' symbol string. Its operating mode is binary.

/kloc-in the 9th century, George Bull, an Irish logician, transformed the thinking process of logical propositions into some kind of algebraic calculus with the symbol "0". "1", binary is binary. 0, 1 is the basic operator. Because it only uses two digital symbols, 0 and 1, it is very simple and convenient, and easy to realize electronically.

Extended data

Reason for adoption:

The implementation of (1) technology is simple, and the computer consists of logic circuits, which usually have only two states, namely, the on-off state of the switch, which can be represented by "1" and "0".

(2) Simplifying operation rules: There are three combinations of sum and product operations of two binary numbers, and the operation rules are simple, which is beneficial to simplifying the internal structure of the computer and improving the operation speed.

(3) Suitable for logical operation: logical algebra is the theoretical basis of logical operation, and the binary has only two digits, which coincides with the "truth" and "false" in logical algebra.

(4) Easy conversion, and easy conversion between binary numbers and decimal numbers.

(5) Using binary to represent data has strong anti-interference ability and high reliability. Because each data has only two states of high and low, it can still be reliably distinguished whether it is high or low when it is disturbed to a certain extent.
