Binary code is a system of representing information or data using a base-2 numeral system. In the binary system, only two digits are used: 0 and 1. Each digit in a binary code is called a "bit" (short for binary digit). These bits are the smallest units of data in computing and digital communication.
Binary code plays a fundamental role in representing data within computers and digital systems. It forms the foundation of all digital computing operations and is used to encode various types of information, including numbers, text, images, audio, and more. Computers and electronic devices use binary code because the underlying hardware components, such as transistors, can easily represent and manipulate two distinct states (on/off or 0/1), making it highly suitable for electronic processing.
For example, to represent text characters using binary code, each character is assigned a unique binary pattern. This pattern consists of a sequence of 0s and 1s that correspond to the character's ASCII (American Standard Code for Information Interchange) or Unicode value. Similarly, images and other forms of data are broken down into binary patterns that can be stored, transmitted, and processed by digital systems.
Overall, binary code is the fundamental language that computers and digital devices use to communicate, process, and store information, forming the basis of modern computing and technology.
