📚 Year 10 SQA Computing: Glossary & Memory Hacks | SQA 计算机词汇术语速记指南
Building a solid foundation in SQA Computing starts with mastering the terminology. This guide provides clear definitions for key terms across all N5 units, paired with memory hacks to help you recall them quickly during exams. Each term is presented in English followed by its Chinese equivalent and a memorable tip.
打好SQA计算机科学的基础要从掌握专业术语开始。本指南为N5课程各单元的关键术语提供了清晰的定义，并配以记忆技巧，帮助你在考试中快速回忆。每个术语先给出英文解释，然后是中文对照和助记提示。
1. Algorithms & Computational Thinking | 算法与计算思维
Algorithm – A step-by-step set of instructions to solve a problem or perform a task. Think of it as a cooking recipe: each step must be clear and in order.
算法（Algorithm）—— 一套逐步执行的指令，用于解决问题或完成任务。你可以把它想象成烹饪食谱：每一步都必须清晰且顺序正确。
Flowchart – A graphical representation of an algorithm using standard symbols such as ovals for start/end, rectangles for processes, diamonds for decisions, and arrows for flow. A common memory aid: "Oval begins, diamond decides, rectangle does the work."
流程图（Flowchart）—— 用标准符号表示算法的图形，例如椭圆表示开始/结束，矩形表示处理，菱形表示决策，箭头表示流程。记忆口诀：“椭圆开头，菱形选择，矩形执行”。
Pseudocode – A simplified, human-readable description of an algorithm that uses natural language and programming-like structures. It helps programmers plan before writing actual code. Remember: it's not a real programming language—it's a planning tool.
伪代码（Pseudocode）—— 使用自然语言和类似编程的结构来描述算法的简化文本。它帮助程序员在编写实际代码之前进行规划。记住：伪代码不是真正的编程语言，而是一种规划工具。
Computational thinking – A problem-solving approach that involves decomposition (breaking a problem down), pattern recognition, abstraction (filtering out unnecessary details), and algorithm design. The acronym DAPA can help: Decompose, Analyse patterns, Pull out abstraction, Assemble algorithm.
计算思维（Computational thinking）—— 一种解决问题的思维方式，包括分解（将问题拆解）、模式识别、抽象（过滤无关细节）和算法设计。助记缩写 DAPA：分解(Decompose)、分析模式(Analyse)、抽象(Pull out)、构建算法(Assemble)。
2. Programming Basics | 编程基础术语
Variable – A named storage location in memory that holds a value which can change during program execution. Imagine a labelled box where you store data. For example, score = 0 assigns the integer 0 to the variable named score.
变量（Variable）—— 内存中的一个命名存储位置，其值在
