How Computers Work

1. How Computers Work

2. What is a Computer?

3. Learning Intentions By the end of the lesson I should be able to: Describe the five main areas of the computer system Show these stages on a Von Neumann State the difference between hardware and software

4. Main Areas of the Computer System Input Devices - Devices that are used with a computer to get data and instructions into the computer. Output Devices - Devices that are used with the computer to get data out to the user. Processor - A chip in the computer that is used to process and execute instructions Backing Storage - Permanent storage that we can save files to so we can access later. Memory - Temporary storage of programs that are running on the computer. This is sometimes called RAM.

10. Von Neumann Diagram – Diagram of the Main Computer Parts! Input Devices Output Devices Processor Backing Storage Memory

11. What is Hardware and Software?

12. What is Hardware and Software? Hardware -  Physical parts of the computer, things you can hold and touch!  e.g mouse, hard drive etc Software -  Programs and apps that are installed on the computer. E.g Word, TickTok

13. Task 1 & 2

14. Build Me a Computer!

15. Success Criteria I now understand: What the main parts of the computer system are. Where each part is on the Von  Neumann diagram.   What the difference between hardware and software is.
