The research directions in computer science and technology are extensive and can be divided into two main sections: theory and application. The core directions include: 

Computer System Architecture: Studies the interaction mechanism between computer hardware and software, covering processor design (such as CPU, GPU architecture), memory hierarchy, parallel computing and distributed systems (such as multi-core technology, cluster architecture), etc. For example, the architecture design of Huawei Ascend chips, and the distributed storage system of supercomputing centers all fall within this category.

Computer Software and Theory: Focuses on the design, development and optimization of software, including programming languages (such as Python, C++), operating systems (such as Linux kernel), compiler principles, algorithm design and analysis (such as dynamic programming, graph theory algorithms), etc.

Computer Application Technology: Integrates computer technology with various industries, covering artificial intelligence (machine learning, deep learning), big data processing (data mining, distributed computing framework Hadoop), computer vision (image recognition, autonomous driving perception), network and information security (encryption technology, firewall design), embedded systems (smart watches, smart home chips), etc.

Database and Information Systems: Studies the storage, management and efficient access of data, including relational databases (MySQL), non-relational databases (MongoDB), data warehouses and data lakes technologies, supporting massive data scenarios in platforms like e-commerce and financial systems.
