What is this?
This is a collection of mind maps and notes covering the core CS graduate exam subjects in China (known as '408'): computer organization, operating systems, data structures, computer networks, and databases, with an added section on information security.
Is this a textbook or a set of mind maps?
It is a set of mind maps (XMind-style diagrams) paired with notes, organized per subject, rather than a full textbook or a curated list of external links.
How do I use this?
Browse the subject folders in the repo and open the mind map files directly; there is no install step since this is a static notes repository.
Which textbooks do these notes follow?
The notes are based on specific Chinese textbook editions: Computer Organization (5th ed., Wang Aiying), Data Structures (Wangdao), Computer Networks (7th ed., Xie Xiren), and Operating Systems (4th ed., Tang Xiaodan).
Can I use this content commercially or redistribute modified versions?
No — the author explicitly states no formal authorization is given for revisions or adaptations, and commercial use is prohibited without permission, despite the repo carrying an Apache-2.0 license.
Does it cover information security too?
Yes, there is a dedicated section on information security alongside the five core 408 subjects, referencing the textbook Cryptography and Network Security by Stallings (6th ed.).
Is there a faster way to download the mind map files if GitHub is slow?
The README mentions alternative download methods, including a mirror on Gitee (码云) for users in mainland China with slow GitHub access.
Can I read the notes online instead of downloading them?
Yes, the README references an online reading site as an alternative to downloading the files directly.
