The research area of binary concerns the study of the binary number system, which is a base-2 numeral system commonly used in computing and digital communications. In binary, numbers are expressed using only two digits, 0 and 1, and rely on powers of 2 for positional notation. This research area includes the study of binary arithmetic, conversion between binary and decimal numbers, binary codes, binary logic operations, and various applications of binary in computer science and technology. Additionally, research in binary may also involve studying binary data representation, binary algorithms, and binary information processing.
