What does Binary mean?
## Definition

Binary is a numeral system that uses only two symbols, 0 and 1, to represent numbers. It is the foundation of digital electronics and computers, as computers use binary to process and store information. In binary, each digit represents a switch that can either be on or off, and these binary digits, or bits, are used to perform complex operations through simple binary calculations. For example, the binary number 10011011 can represent the decimal number 155, allowing computers to perform mathematical operations with decimal values by converting them to binary. Binary is also used in coding and data compression, where it is used to represent text, images, and other data in a compact and efficient manner. The use of binary allows for efficient processing and storage of data, as well as easy transmission between computers and other digital devices. In short, binary is a crucial part of the digital world, providing a simple and efficient way to represent and manipulate data in computers and other digital devices.
