The binary system is a numerical system that uses two symbols, typically 0 and 1, to represent values. It’s the fundamental language of computers and digital technology, where data is represented using binary digits, or bits. In the binary system, each digit’s position represents a power of 2. For example, in the binary number 1101, the rightmost digit represents 2^0 (1), the second digit from the right represents 2^1 (2), the third digit represents 2^2 (4), and the leftmost digit represents 2^3 (8), summing up to a total value of 13.
