What Is Binary (Definition)? – POFTUT

# 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.

# 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.
