01Programming and Software Development
This shared-core programming guide covers language constructs, object-oriented design, development processes, and testing. Practice reading and debugging code: predict output, identify a scope or logic error, and choose tests that expose faults.
367 words, about 2 min02Computational Thinking and Problem Solving
This shared-core guide develops decomposition, pattern recognition, abstraction, algorithm design and tracing, and evaluation. Use pseudocode and search/sort scenarios to practice predicting output, identifying missing steps, and justifying complexity.
361 words, about 2 min03Computer architecture, logic and data representation
This domain examines the stored-program machine: how instructions and data share one memory, how the processor fetches and executes them, and how the memory hierarchy and instruction-set design affect performance. Instructions and data share one memory and one set of buses.
713 words, about 4 min04Operating systems, translation and concurrency
Understand the OS as a resource manager and extended machine: process management, CPU scheduling (FCFS, SJF, priority, round robin), process states and the PCB, context switching, threads versus processes, and inter-process communication. Study synchronization: critical sections, mutexes, semaphores, and deadlock's four necessary conditions (mutual exclusion, hold and wait, no preemption, circular wait).
494 words, about 2 min05Requirements, design, testing and architecture trade-offs
Know the software development life cycle: requirements, analysis, design, implementation, testing, deployment, and maintenance. Compare process models - waterfall, incremental, spiral, prototype, and agile/Scrum - and when each fits.
503 words, about 3 min06Data, Databases, and Information Retrieval
Data questions move from raw facts to organized, queryable information. In the relational model, tables have rows (records) and columns (attributes); keys enforce identity and relationships.
468 words, about 2 min07Computer Network Fundamentals and Architecture
The fundamentals domain is the frame everything else hangs on. This chapter develops whether you can place a function, a PDU, a device or a standard at the correct layer, and whether you can compute channel capacity and delay - not whether you can merely recite layer names.
482 words, about 2 min08Security foundations, governance and Chinese context
This domain covers the vocabulary and models that every later domain assumes: what security protects, how it is decomposed, and the formal rules that describe access control. NISP Level 1 questions here are usually definitional, so precision matters more than depth.
917 words, about 5 min09Secure development, review and software supply chain
Secure software development integrates security requirements, design, implementation, testing and maintenance. Begin with intended users, data, business functions and misuse cases.
