01Computer 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 min02Embedded hardware, interfaces and timing assumptions
An embedded system controls or observes a particular environment through a specified processor, memory and input/output design. A microcontroller commonly integrates a processor core with peripherals, but the actual memory map, bus widths, interrupt rules and register semantics come from its documentation.
464 words, about 2 min03Real-time scheduling, firmware lifecycle and dependable state
A real-time requirement specifies when an observable result must occur, not simply that the processor is fast on average. Define period, release, deadline, execution time and allowed jitter for the actual task.
463 words, about 2 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 min05Programming 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 min06Computational 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 min07Requirements, 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 min08Secure 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.
438 words, about 2 min09Security 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.
