What are instructions? What are the two parts of a computer's instructions?

The instruction is the basic operation that the computer can realize, and it is the instruction and command that directs the machine to work. The instruction is in the form of binary number.

The controller directs the machine to work by instructions, and people use instructions to express their intentions and hand them over to the controller for execution.

Usually an instruction includes two aspects: the opcode and the Operand, the opcode determines the operation to be completed, and the Operand refers to the data participating in the operation and the address of the unit in which it is located.

In a computer, operation requirements and Operand addresses are represented by binary numbers, called opcodes and address codes, respectively, and the whole instruction is stored in memory in the form of binary coding.

What is a program?

A program is a group of instructions that can be recognized and executed by a computer. it is a collection of instructions or commands that run on an electronic computer and meet certain needs of people.

It is written in some programming languages and runs on a certain target architecture. For example, a program is like an article written in English (programming language). Let a person who knows English (compiler) also read, understand and mark this article (structural system). Generally speaking, computer programs based on English text are compiled and linked to make it difficult for people to interpret, but they can be easily interpreted by the computer and then put into operation.
