3. Core Topic: Computational Thinking | 核心主题：计算思维
Computational thinking is the problem-solving framework at the heart of CCEA Computer Science. It consists of four pillars: decomposition, pattern recognition, abstraction, and algorithm design.
计算思维是CCEA计算机科学核心中的问题解决框架，由四大支柱组成：分解、模式识别、抽象和算法设计。
Decomposition means breaking a complex problem into smaller, manageable parts. For example, creating a game can be split into graphics, logic, and user input.
分解是指将复杂问题拆分成更小、更易处理的部分。例如，制作一个游戏可以分为图形、逻辑和用户输入。
Pattern recognition involves identifying similarities or common features among different problems, which helps in reusing solutions. This is why spotting that a sequence is repeated is useful in coding.
模式识别涉及在不同问题中识别相似性或共同特征，这有助于重用解决方案。这就是为什么在编程中发现重复序列是有用的。
Abstraction focuses on filtering out unnecessary details to model a problem. A map is an abstraction of the real world—showing only roads, not every tree.
抽象专注于滤除不必要的细节以对问题建模。地图就是对真实世界的一种抽象——只显示道路，不显示每一棵树。
Algorithm design is the process of creating step-by-step instructions to solve a problem. You will learn to express algorithms using pseudocode and flowcharts.
算法设计是创建分步指令以解决问题的过程。你将学习使用伪代码和流程图来表达算法。
4. Core Topic: Data Representation | 核心主题：数据表示
Computers store all data as binary digits—0s and 1s. Understanding how numbers, text, and images are represented is essential for the Computer Systems unit.
计算机以二进制数字（0和1）存储所有数据。理解数字、文本和图像的表示方式对于计算机系统单元至关重要。
A single binary digit is a bit; eight bits make a byte. A nibble is four bits. You need to be comfortable converting between denary (base 10), binary (base 2), and hexadecimal (base 16).
一个二进制数字是一位；八位组成一个字节。四位被称为半字节。你需要熟练掌握十进制（基数为10）、二进制（基数为2）和十六进制（基数为16）之间的转换。
Here is a quick conversion table for nibbles:
下面是一个半字节的快速转换表：
| Denary | Binary | Hexadecimal |
|---|---|---|
| 0 | 0000 | 0 |
| 5 | 0101 | 5 |
| 10 | 1010 | A |
| 15 | 1111 | F |
o denary, add the place values where a 1 appears. For example, 1101₂ = 8 + 4 + 0 + 1 = 13.
要将二进制转换为十进制，将出现1的位权值相加。例如，1101₂ = 8 + 4 + 0 + 1 = 13。
Characters are represented using character sets such as ASCII and Unicode. Each character is assigned a unique binary number.
字符使用ASCII和Unicode等字符集来表示。每个字符被分配一个唯一的二进制数。
Hexadecimal is a shorthand for binary, often used for memory addresses and colour codes. A two-digit hex number can represent a byte.
十六进制是二进制的缩写，常用于内存地址和颜色代码。一个两位的十六进制数可以表示一个字节。
5. Core Topic: Hardware and Software | 核心主题：硬件与软件
