Binary By nick bailey

What is binary?

Binary, also known as base 2, is a counting system made up of ones and zeroes that is used by computers. It works by having two possible values for each digit, 1 and 0. The amount of digits in any given binary number is measured in 'bits', so for example a 2-bit number has three possible values: 00; 01; 10 and 11. 'Bit' is short for 'binary digit'

Why do computers use binary?

Computers use the binary system to count because it reflects their only states for circuits, on or off. This means, were they to use the decimal system, they would have to have another eight states for circuits to be in, so the binary system is a lot easier for computers to process.

How do you convert decimal numbers tO binary?

In our decimal number system (also known as base 10), each digit is a representation of how many of each power of 10 (1, 10, 100, 1000, etc) there are. For example, in the number 546, there are 6 ones (10^0), 4 tens (10^1) and 5 hundreds (10^2). However, in binary (or base 2), each digit represents a power of 2 instead. For example, in the number 11010, there are 0 ones (2^0), 1 two (2^1), 0 fours (2^2), 1 eight (2^3) and 1 sixteen (2^4). This means the number 11010 in decimal is 26 in decimal. You can also express this as a table:
