Lesson 2: What's inside a Computer?

Year 9 – Introduction to Computer Hardware

Lesson objectives 

Conquer: Understand that a computer is made up of a range of components.

Aspire: List a range of components that are found in a computer and explain their function.

Hardware components guide 

• You are going to create a guide of all the hardware components we use inside of a computer.

• This guide will contain information about what each part does along with images for reader to look at.
  

 

The CPU

• CPU stands for Central Processing Unit.

• The CPU is known as the brain because it is used to process data and instructions

                                      

•                                         This is a CPU, its very small and takes up very little space inside the PC.

 

Hardware components guide 

• Create a PowerPoint titled “Hardware components” or open the one you made last week. 

• Slide 1 - The CPU:  Find an image of the CPU and add it.
•  State what CPU is short for and what it does.
  

• Extension: Find an image of a body part we can use to represent the CPU.

If students finish the 2 tasks and the extension, ask them to design their hardware guide, or a cover slide to introduce it., 

The Motherboard

• The motherboard is the main circuit board of a computer.

• All components (parts) of the computer are connected to the motherboard, even the CPU. 

• The motherboard acts like the skeleton because it connects everything.                                     

•

Slide 2 - The Motherboard:  Find an image of a motherboard and add it.

• State the purpose of a Motherboard.
  

• Extension: Find an image of a body part we can use to represent the Motherboard.

The Hard Drive 

• The hard drive is the computer’s long-term memory. All programs and files (Pictures, videos, documents, games)  are stored.

• It doesn’t matter how many times you turn your computer on or off, the programs and your data will always be there. 
• 
                                   

•

Slide 3 - Hard Drive:  Find an image of a Hard Drive and add it.

• State the purpose of a Hard Drive.
  

• Extension: Find an image of a body part we can use to represent a Hard Drive.

Graphics card

• A graphics card displays images and videos on your monitor.

• Modern graphics cards come with in built fans to keep then cool.

• Often modern graphics card are the most expensive part of a pc build.                        

 

Hardware components guide 

Slide 4 - Graphics card:  Find an image of a Graphics card and add it.

• State the purpose of a graphics card.

• Extension: What is the name and price of the most expensive graphics card in the world.?

The Quadro-GV100, selling for over $8,000, is considered the most expensive GPU ever manufactured.

Post end of lesson quiz/afl if time permits. 

Sort the pc parts from the input and output devices. 

Computer parts

Input/Output device.

Touch Screens

A touch screen is the only device which works as both an input and an output device.

You view the options available to you on the screen (output) and you then use your finger to touch the option that you have chosen (input).

Create a hardware guide.

In PowerPoint (Click here) create 3 slides

1. Slide 1 - What is a computer?
2. Slide 2 - What are input devices?
3. Slide 3 - What are output devices. 

Include the key definition and image examples of devices.
