What Is Binary (Definition)?


Binary is a numbering system used to express numbers in 2 states. These two states are 0 and 1. The binary numbering system is very important for computer and IT systems because the different type of hardware uses a binary system like CPU, RAM, GPU, HDD, NIC, etc.

Binary Values

Binary numbering system provides two values named and 1.  There is no number like 3, 5 or similar in binary. Computers mainly use these binary values in order to process, read, write data.

Boolean Logic

Binary numbers are highly related with the boolean logic. Boolean Logic is a logic which is mainly used in computers and mathematics. binary values are used to express the false logic where 1 is used to express the true logic. We can also use different logic operators like AND, OR, EXOR etc. Here are some Boolean Logic calculations with binary values.

1 AND 1 = 1

1 OR 0 = 1

1 AND 0 = 0

1 XOR 0 =1

1 XOR 1 = 0

Binary and Decimal Numbers

Binary numbers can cen be converted into decimal numbers and vise versa. For example 11 binary value is equal to 3 in decimal numbering system.

Decimal Value Binary Value Base-2 Representation
n/a
1 1 2
2 10 21
3 11 21 + 2
4 100 22
5 101 22+ 2
6 110 22 + 21
7 111 22 + 21 + 2
8 1000 23
9 1001 23 + 2
10 1010 23 + 21
64 1000000 26
256 100000000 28
1024 10000000000 210
