Show understanding that a stack, queue and linked list are examples of ADTs
Describe the key features of a stack, queue and linked list and justify their use for a given situation
Use a stack, queue and linked list to store data
(You will not be required to write pseudocode for these structures, but they should be able to add, edit and delete data from these structures)
Describe how a queue, stack and linked list can be implemented using arrays

Create a PowerPoint and a poster including the three parts above including the PC or laptop with the latest technology used on them such as hardware component (for example maximum storage devices HDD, CPU, RAM, Motherboard, ….etc), why some of the PCs or laptops are more expensive than others, what makes them so expensive in term of what ?
What are the main Components of a Computer System?
Gives and Example of Input and Output devises
Gives an example of an Operating Systems
After you create a PowerPoint and a poster, you should present and explain at the front of the class your project
In this chapter you will learn about:
1.3.3 Input devices
•• describe the principles of operation (how each device works) of these input devices: 2D and 3D scanners, barcode readers, Quick Response (QR) code readers, digital cameras, keyboards, mice, touch screens, interactive whiteboards, microphones.
•• describe how these principles are applied to real-life scenarios, for example: scanning of passports at airports, barcode readers at supermarket checkouts, and touch screens on mobile devices.
•• describe how a range of sensors can be used to input data into a computer system, including light, temperature, magnetic field, gas, pressure, moisture, humidity, pH and motion
•• describe how these sensors are used in real-life scenarios, for example: street lights, security devices, pollution control, games, and household and industrial applications.
1.3.4 Output device
•• describe the principles of operation of the following output devices: inkjet, laser and 3D printers; 2D and 3D cutters; speakers and headphones; actuators; flat-panel display screens, such as Liquid Crystal Display (LCD) and Light-Emitting Diodes (LED) display; LCD projectors and Digital Light Projectors (DLP).
•• describe how these principles are applied to real-life scenarios, for example: printing single items on demand or in large volumes; use of small screens on mobile devices.
Describe the purpose of an operating system (You will be required to understand the purpose and function of an operating system and why it is needed. you will not be required to understand how operating system work.)
Show understanding of the need for interrupts
Show understanding of the basic Von Neumann model for a computer system and the stored program concept (program instructions and data are stored in main memory and instructions are fetched and executed one after another)
