Application instructions can be divided into the following five types: 1. Control instructions, used to control the execution flow of the program; 2. Data processing instructions, used to operate and calculate data; 3. Input and output Instructions are used to input and output data with external devices; 4. Transfer instructions are used to switch between different code segments in the program; 5. Privileged instructions are some programs that only have operating systems or higher privilege levels instructions that can be executed.
# Operating system for this tutorial: Windows 10 system, Dell G3 computer.
Application instructions can be divided into the following types:
Control Instructions: Control instructions are used to control the execution flow of the program, including conditional judgments , loops and jumps, etc. For example, if statements, for loops, while loops, jump statements, etc.
Data Processing Instructions: Data processing instructions are used to operate and calculate data. These instructions can perform various operations such as addition, subtraction, multiplication and division, logical operations, bit operations, shifts, etc. For example, addition instructions, multiplication instructions, logical AND or NOT instructions, etc.
Input/Output Instructions: Input and output instructions are used to input and output data with external devices. They enable applications to interact with the user, read input data from the keyboard, display results to the screen, or read and write files, etc. For example, read input instructions, display output instructions, read file instructions, etc.
Transfer Instructions: Transfer instructions are used to switch between different code segments in the program. These instructions are used to jump to different subroutines, functions, or code labels to complete a specific operation. For example, function call instructions, return instructions, jump instructions, etc.
Privileged Instructions: Privileged instructions are instructions that only the operating system or programs with higher privilege levels can execute. These instructions are used to perform specific system-level operations, such as accessing underlying hardware, modifying kernel state, etc.
The above are some common types of application instructions and are not exhaustive. In fact, the classification of instructions may also vary depending on the architecture and specific programming language. Different computer architectures and programming languages may have their own specific instruction sets and instruction types.
