What Are Binary Numbers?
The binary system is a positional number system based on 2. Binary logic says that the number 1 is 'true' and the '0' is false. The main use of the binary system is computers. The binary system is used by almost all modern computers and devices. The basis of all digital data is binary representation.
In a binary system numbers are presented in the same way as in a decimal system or in any other positional number system. The difference from the decimal system lies in the fact that the base of the decimal system is 10 and, accordingly, the number plates are 10 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). All binary numbers are combinations of digits 0 and 1.
In the binary system, the counting is performed as follows: 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001 etc. A multi-digit number must be read in the same way as each place is a separate number, for example:10 must read 'one, zero', not 'ten'. To use only two symbols (0 and 1), you must use both of the two decimal places to make the decimal point 2:10. The smallest position (2°=1) changes every two, then every four digits, after each eight digits etc. Each subsequent successive sequencer is twice as large as the previous one. The binary system is the easiest positional number system.
