is 16-bit, then the processor is said to be 16-bit.

the instruction code digital computer is a universal digital system. A general digital computer can perform various micro-operations, and it can also specify which specific operation sequences it must perform. The user of the system can control the processing process through a program, which is a set of instructions that specify operations, operation codes and execution processing sequences. By writing new programs with different instructions or inputting different data for the same instruction, the task of data processing can be easily changed. A computer's instruction is a binary generation that specifies the sequence of computer micro-operations.
