# Binary

Tags: Glossary

A computer term referring to a system of numerical notation that assumes only two possible states or values: zero (0) and one (1). Computer systems use a binary technique where an individual bit or 'Binary Digit' of data can be 'on' or 'off' (1 or 0). Multiple bits are combined into a 'Byte', which represents a character or number.

## What is Binary?

Binary is a fundamental concept in the world of computers and technology. It refers to a system of numerical notation that is based on only two possible states or values: zero (0) and one (1). This may sound simple, but it forms the foundation of how computers process and store information.

In binary, each digit is called a bit, which is short for "binary digit." A bit can be either "on" or "off," represented by the values 1 and 0, respectively. These two states are analogous to the concept of a light switch being either turned on or off. By combining multiple bits together, we can represent more complex information.

The basic unit of binary information is called a byte. A byte consists of eight bits, and it can represent a character or a number. For example, the letter 'A' can be represented by the binary value 01000001. Each bit in the byte contributes to the overall value, allowing us to represent a wide range of characters and numbers.

The binary system is essential for computers because it aligns with the physical nature of electronic circuits. Computers use electronic switches that can be in one of two states: on or off. By assigning the values 1 and 0 to these states, we can represent and manipulate information using electrical signals.

One of the advantages of the binary system is its simplicity. Unlike decimal, which uses ten digits (0-9), binary only requires two digits (0 and 1). This simplicity makes it easier for computers to process and store information. Additionally, binary operations are well-defined and predictable, which is crucial for the reliable functioning of computer systems.

Binary is not only used for representing numbers and characters but also for performing calculations and logical operations. By using binary arithmetic, computers can add, subtract, multiply, and divide numbers. Logical operations, such as AND, OR, and NOT, are also performed using binary.

Understanding binary is essential for anyone interested in computer science or technology. It forms the basis for various concepts like data storage, communication protocols, and computer programming. By grasping the fundamentals of binary, beginners can gain a deeper understanding of how computers work and how information is processed in the digital world.

In conclusion, binary is a system of numerical notation that uses only two possible states or values: zero and one. It is the foundation of how computers process and store information. By combining bits into bytes, we can represent characters and numbers. Binary is simple, reliable, and essential for various computer operations.
