In simple terms, it controls all operations and functions of a computer. **Basic Knowledge** 1. Composition: The CPU is mainly composed of a controller, an arithmetic logic unit (ALU), and registers. The controller is responsible for reading and executing instructions; the ALU performs arithmetic and logical operations; and registers are used to store data and instructions. 2. Number of cores: The number of cores in a CPU refers to the number of processors inside it. The more cores, the stronger the ability to handle multiple tasks. 3. Architecture: The architecture of a CPU determines its performance and functionality, with common architectures being x86, ARM, etc. **Performance Metrics**

1. Clock speed: The higher the clock speed, the faster the CPU can process information. 2. Cache: The size and type of cache determine how quickly and efficiently the CPU can access memory. 3. Process technology: The more advanced the process technology, the lower the power consumption and heat generation of the CPU, and the better its performance. 4. Core architecture: New core architectures can improve performance and reduce power consumption. **Application Scenarios** 1. Gaming and entertainment: CPUs play a key role in gaming performance, with high-clocked, multi-core CPUs providing a better gaming experience. 2. Office applications: Daily office software such as Word and Excel mainly rely on the computing power of the CPU. 3. Image processing and video editing: For tasks that require processing large amounts of data, such as image processing and video editing, high-performance CPUs can greatly improve work efficiency.

**How to Choose a CPU** 1. According to Usage: Choose a CPU that suits your needs and budget. If主要用于办公或娱乐，中端处理器已足够; For gaming, design, and video editing demands, you may need to consider high-performance CPUs. 2. Compare Performance Metrics: Consider factors like clock speed, number of cores, cache size when choosing a CPU. For large games and high-end applications, it's recommended to choose a CPU with more cores and a higher clock speed. 3. Brand and After-sales Service: Choose a well-known brand with good after-sales service guarantees. **Mastering the Advanced Level
