Anything larger and the computer would need to break the number into smaller pieces. 16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time. Today, 16-bit hardware and software has been replaced by 32-bit and 64-bit alternatives, which give the computer more memory to work with; increasing overall performance. For example, early computer processors (e.g., 8088 and 80286) were 16-bit processors, meaning they were capable of working with 16-bit binary numbers (decimal number up to 65,535).
