This repository contains study notes and mind maps covering the core subject areas tested in China's national graduate school entrance exam for computer science, commonly referred to as exam 408. The 408 exam covers four mandatory topics: computer organization and architecture, operating systems, data structures, and computer networks. This repository covers all four, plus two additional subjects: databases and information security. The notes are based on specific Chinese textbooks. Computer organization follows the fifth edition by Wang Aiying, operating systems follows the fourth edition by Tang Xiaodan, data structures follows the Wang Dao study guide, and computer networks follows the seventh edition by Xie Xiren. The databases section references the fifth edition by Wang Shan and Sa Shixuan, and information security references a translated edition of a textbook by Stallings. The primary format is mind maps, which are branching visual diagrams that organize information hierarchically. They are useful for memorization and for getting an overview of how topics relate to each other within a subject. The repository links to rendered versions of these mind maps and an online reading site. A mirror on the Chinese platform Gitee is also available for users who find GitHub download speeds slow from within China. The content is in Chinese and appears to be created by a single author for personal study use.
