The editor would like to share with you what the instructions in the application programs in the computer network can be divided into. I hope you will gain something after reading this article. Let's discuss it together.

Instructions in an application can be divided into two categories: the instruction set of the CPU and the request for specific services from the operating system. An instruction consists of one or more bytes, including opcode fields, one or more fields about the address of operands, and some status words and signatures that represent the state of the machine.

The operating environment of this tutorial: windows10 system, Dell G3 computer.

Theoretically, instructions in an application can be divided into two categories: the instruction set of the central processing unit (CPU) and the request for specific services from the operating system.

Central processing unit (CPU,Central Processing Unit) is a very large-scale integrated circuit, which is the operation core (Core) and control core (Control Unit) of a computer. Its main function is to interpret computer instructions and process data in computer software. The processing flow of CPU operation instruction is roughly divided into several steps: fetch, decode, execute, access memory, write back and so on.

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

The command that a computer program sends to a computer processor is "instruction". The lowest instruction is a string of zeros and 1s, indicating that an entity job operation is to be run (such as "Add"). Depending on the type of instruction, a specific storage area is called a "register", which contains data or data storage locations that can be used to call out instructions.

Form of composition:

An instruction is a command that instructs the computer to perform an operation. It consists of a string of binary numbers. An instruction usually consists of two parts: opcode + address code.

Opcode: indicates the type or nature of the operation to be performed by the instruction, such as fetching, adding, or outputting data, etc.

Address code: indicates the content of the operation object or the address of the storage unit in which it is located.

The execution program of the instruction:

The sequential execution of instructions will complete the execution of the program, so it is necessary to understand the execution process of instructions. The first is to fetch instructions and analyze instructions. According to the order specified by the program, the currently executed instructions are taken from the internal memory and sent to the instruction register of the controller to analyze the instructions, that is, to determine what the computer should do according to the operation code in the instructions.

The second is to execute instructions. According to the result of instruction analysis, the controller sends out a series of control potentials needed to complete the operation in order to direct the relevant parts of the computer to complete the operation and to prepare for the next instruction.
