部件01:计算机系统:(50%)

向学生介绍的中央处理单元(CPU),计算机存储器和存储,有线和无线网络,网络拓扑,系统的安全性和系统的软件。它也着眼于与计算机科学相关的伦理,法律,文化和环境问题。

单元1级的系统的体系结构:

In this unit you will learn about: The purpose of the CPU, The Von Neumann architecture, Common CPU components and their function, How common characteristics of CPUs affect their performance & Embedded systems

In addition you will learn about: The purpose of Memory: What is meant by RAM, Virtual Memory & ROM. You will also look at various storage devices and in what situation is best to use each type.

Unit 2: Wired & Wireless Networks:

In this unit you will look at Network topologies such as MESH, star, LAN & WAN. In addition you will look at network protocols & layers.

Unit 3: Systems Software & Security:

在这个单元中,你将看到多种安全威胁,衡量你能落实到位,以防止这些利用技术,如:加密,防病毒,防恶意软件等。

Unit 4: Ethical, Legal & Cultural Issues:

In this unit we explore the evolution of computers over time and how this has had an impact on us, the laws that protect us and the different impact in relation to the Social & moral issues.

部件02:计算思维,算法和程序设计:(50%)

学生申请的知识和组件01.理解获得他们开发计算思维能力和理解:算法,程序设计技术,生产健壮的程序,计算逻辑,翻译和数据表示。此组件内开发的技能和知识,在完成规划项目时,将支持学习者。

单元5:算法:

在这个单元中,你学会了思考有关自己的部分方面的问题。部分可以理解,解决和发展拿出一个解决方案。你也将看到不同的搜索和排序算法

单元6:编程:

In this unit you will explore programming concepts such as sequence, selection & iteration. You will look at using procedures & functions in your created programs along with file handling such as reading/writing to a CVS/txt file.

Unit 7: Logic & 语言sP:

In this unit you will explore how computers use binary to represent binary. In addition you will look at logic gates and logic circuits including AND, NOT & OR gates along with truth tables and how to interpret logic circuits

单元8:数据表示:

In this unit you will explore how computers use binary to represent binary. You will perform some conversions from Denary to Binary & Hexadecimal and look at how images & sound are represented in binary. You will also look at how images and sound are represented in binary form.

组件03的编程项目:

学生使用OCR编程项目任务,开发在组件01和02,他们将有机会从一个给定的问题定义成功的标准开发的技能学生的实践能力,然后创建合适的算法来实现成功的标准。学生然后在适当的编程语言代码的解决方案,并使用合适的并记录测试计划检查其功能。最后他们将评估他们的解决方案的成功,反映对未来可能的发展。

学生应提供20小时安排发出的时间来完成他们的编程项目。编程项目不计入候选人的最终成绩,但课程的要求。

回顾一周 - 使学习难忘

As part of marking learning memorable, student will spend review week undertaking a project based on Cycle 1, 2 and 3 during review week 1, and then cycle 4, 5 & 6 as part of review week 2

资源:
学生有访问谷歌的教室在那里他们可以查看课程中使用的资源,并询问有关特定主题的问题,如果他们需要这样做出来的学习时间。
