The binary number system, a fundamental concept in computing, is a method of representing numerical data using only two digits: 0 and 1. For instance, the decimal number 5 is represented as 101 in binary.
Binary is widely used due to its simplicity, efficiency, and versatility. It forms the foundation of digital computers, facilitating data storage, processing, and transmission. The inception of the binary system can be traced to the 17th century, with renowned mathematician and philosopher Gottfried Leibniz playing a significant role in its development.
