1. Exam Overview and Assessment Objectives | 考试概览与评估目标
The CIE Year 8 Computing exam is designed to test knowledge, application, and problem-solving skills. Typically, the paper is divided into two sections: Section A with multiple-choice or short-answer questions, and Section B with structured questions that may ask you to trace an algorithm or write code. The assessment objectives (AOs) focus on recalling facts (AO1), applying concepts to scenarios (AO2), and evaluating solutions (AO3).
CIE Year 8 计算机考试旨在考查知识、应用和解决问题的能力。试卷通常分为两部分：A 部分为选择题或简答题，B 部分为结构化问题，可能要求你跟踪算法或编写代码。评估目标（AO）包括记忆事实（AO1）、将概念应用于情境（AO2）以及评价解决方案（AO3）。
To excel, you must be familiar with command words: 'State' means give a brief fact; 'Describe' requires more detail; 'Explain' asks for reasons; and 'Compare' demands similarities and differences. Practising with past papers helps you decode these prompts quickly.
要取得好成绩，你必须熟悉指令词：'State' 表示给出简短的事实；'Describe' 要求更多细节；'Explain' 要求说明原因；'Compare' 需要比较异同。通过历年真题练习，你能快速解读这些提示。
2. Computer Systems and Hardware: Common Past Paper Questions | 计算机系统与硬件：历年常见真题
A favourite exam topic is identifying hardware components and describing their functions. Common questions ask about the CPU, RAM, ROM, and input/output devices. For example, a past paper might ask: 'Explain the difference between RAM and ROM.'
热门的考试主题是识别硬件组件并描述其功能。常见问题涉及 CPU、RAM、ROM 以及输入/输出设备。例如，真题可能会问：'解释 RAM 和 ROM 的区别。'
Model answer (English): RAM (Random Access Memory) is volatile memory that temporarily stores data and instructions currently in use by the CPU; its contents are lost when the power is turned off. ROM (Read Only Memory) is non-volatile memory that permanently stores the boot-up instructions (BIOS) and cannot be easily modified.
标准答案（中文）：RAM（随机存取存储器）是易失性存储器，临时存储 CPU 正在使用的数据和指令；断电后内容会丢失。ROM（只读存储器）是非易失性存储器，永久存储启动指令（BIOS），且不易被修改。
Another common question: 'Identify two input devices used in a supermarket checkout system and explain their purpose.' Answers could include a barcode scanner (input) to read product codes, and a touch screen (input) for operator commands. Always link the device to its function.
另一个常见问题：'指出超市结账系统中使用的两种输入设备，并说明其用途。' 答案可以包括：条码扫描器（输入）读取商品代码，触摸屏（输入）用于操作
