The term "256 (Square)" refers to the mathematical operation of squaring the number 256. When a number is squared, it is multiplied by itself. Therefore, 256 squared equals 256 × 256, which results in 65,536. This operation is commonly used in various fields, including mathematics and computer science. In computing, the number 256 is significant because it represents the total number of values that can be represented with one byte. A byte consists of 8 bits, and with each bit having two possible states (0 or 1), the total combinations are 2^8, which equals 256. This concept is fundamental in digital systems and data representation.
