Lesson 1: How does a digital device work? Year 3 – Computing systems and networks – Connecting computers  Objectives Lesson 1: How does a digital device work? To explain how digital devices function I can explain that digital devices accept inputs I can explain that digital devices produce outputs I can follow a process I can explain what makes a secure password  Introduction What do these things have in common? All of these things either are digital devices or use digital devices inside them to make them work.  Activity 1 Sort these items into two groups Why did you sort them that way?  Activity 1 They could be sorted like this...  Activity 2 Digital devices must have an input, a process, and an output Process Input Output When ‘H’ key Hello world pressed, display ‘H’ When ‘e’ key pressed, display ‘e’ When... You press a button The computer follows a You see the letter on on the keyboard program that tells it the screen that what to do when you matches the button press a button that you pressed  Activity 2 ‘Input, process, output’ machine 2 5 input Process: make it Process: Process: add 2 double bigger it output 4 7  Activity 2 Input, process, output Can you find the inputs, processes, and outputs for the machines on the sheet?  Activity 2 Input, process, output – Answers Did you find the different inputs, processes, and outputs?  Activity 3 What is a cyber-attack? When criminals try to steal our online information without our permission. 10  Activity 3 Which of these password is the most secure? Password12 Dogc&tmeAn25 fredsmith65 https://www.security.org/how-secure-is-my- password/ 11  Plenary What have you learnt? What is this digital device? What does it do? What is the input? What is the process? What is the output? How can we protect our data?  Assessment How confident are you? (1–3) I can explain that digital devices 3 – Very confident accept inputs I can explain that digital devices produce outputs 2 – Unsure I can follow a process I can explain what makes a secure password 1 – Not confident  Summary Next lesson In this lesson, you... Next lesson, you will… Used an ‘input, process, output’ Look at devices with different inputs machine and understood what and outputs and design your own makes a secure password digital device
