Operation code

Updated: 10/01/2023 by Computer Hope

Sometimes called opcode, operation code is code that instructs the computer on what instruction it should perform. These machine instructions may include such tasks as "add" and "input" and may specify the data to process, in the form of operands.


Operation code may also be called instruction code, instruction machine code, instruction parcel, instruction syllable, opstring, or order code.
