Does a statement in a computer consist of an opcode and an operand?

Computer instructions (statements) 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.

An instruction is a statement in machine language. It is a set of meaningful binary codes. The basic format of the instruction is such as: operation code field and address code field. The opcode specifies the operation nature and function of the instruction, and the address code gives the operand or the address of the operand.

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.
