binary number system راژمان ِ عددهای ِ درینی râžmân-e adadhâ-ye dirini
*Fr.: système des nombres binaires*
A → *numeral system* that has 2 as its base and uses
only two digits, 0 and 1. The positional value of each digit in a binary number
is twice the place value of the digit of
its right side. Each binary digit is known as a bit. The decimal numbers from 0 to 10
are thus in binary 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, and 1010.
And, for example, the binary number 11101_{2} represents the decimal number
(1 × 2^{4}) + (1 × 2^{3})
+ (1 × 2^{2}) + (0 × 2^{1}) + (1 × 2^{0}),
or 29. In electronics, binary numbers are the flow of information in the form
of zeros and ones used by computers. Computers use it to manipulate and store all of
their data including numbers, words, videos, graphics, and music. → *binary*; → *number*;
→ *system*. |
