#Computer instructions are composed of two parts, they are operation codes and operands.

Computer instruction format usually contains two parts: opcode and operand.

Computer instructions are instructions and commands that direct the work of the machine. A program is a series of instructions arranged in a certain order. The process of executing the program is the working process of the computer.

The controller relies on instructions to direct the machine to work. People use instructions to express their intentions and give them to the controller for execution.

Usually an instruction includes two aspects: operation code and operand. The operation code determines the operation to be completed. The operand refers to the data participating in the operation and the unit address where it is located.

In computers, operation requirements and operand addresses are represented by binary numbers, called operation codes and address codes respectively. The entire instruction is stored in the memory in the form of binary encoding.

The type and number of instructions are related to the specific machine model and will not be described in detail here. Please refer to the specific machine data manual.
