What are binary numbers?

Answer 1

A Binary number is a number system to the base of two.

Answer--The binary numeral system, or base-2 number system represents numeric values using two symbols, usually 0 and 1. More specifically, the usual base-2 system is a positional notation with a radix of 2. Owing to its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by all modern computers.

Eg:0-0

1-1

2-10

3-11

4-100

5-101

6-110

7-111

8-1000
There is no "the" binary number, although there is "a" binary number.

Binary is a system of numbers whch uses only 0 and 1 (or off and on), such as 010101010101101110. This is mainly used by computers. Another meaning of binary numbers is the possible numbers using binary with a certain number of digits. These numbers are 2 to the power of X where X is the numberof digits. There is no "the" binary number, although there is "a" binary number.

Answer 2

Computers are built from collections of

switches which can be either on (1) or off (0).

Decimal numbers are converted into binary

and the computations are done by switches

flipping from off to on or from on to off.

Answer 3

Bianary is the backbone of computer storage, in the hard drive and flash memory there are microscopic sectors that either contain 0 or 1, they use 0 or 1 as this is the simplest thing for a computer to understand and then when the computer reads it deciphers it in to something meaning full on your computer screen like a word document.

Answer 4

The only numbers involved in the binary number system are one and 0. They are called binary numbers because it relates to exponents of the number two.

Answer 5

It's a base-2 numeral system which represents a numeric value using a combination of 0's and 1's
