Lesson 2: What parts make up a digital device? Year 3 – Computing systems and networks – Connecting computers  Objectives Lesson 2: What parts make up a digital device? To identify input and output devices I can classify input and output devices I can describe a simple process I can design a digital device  Introduction 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?  Introduction 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 1 Input or output? keyboard printer webcam cable microphone monitor input mouse output touchscreen speakers  Activity 1 Input or output? crossing lights crossing button input output  Activity 2 Device inputs and outputs Input device Digital device Output device Keyboard Laptop Printer Touchscreen Games console Screen Games controller Tablet Speaker Button Pedestrian crossing Pedestrian button crossing lights  Activity 3 Design a digital device Can you design a machine that uses Some ideas inputs and produces an output? A device that: Can you describe how its processing works? Makes lights flash to music Tells jokes Takes a picture and changes it Records a voice and changes it Makes music  Activity 3 Design a digital device Devices Process Inputs Dazzling disco lights Invention name: ___________________________ Music from the disco goes into the Different coloured lights that flash microphone. The device measures how loud the music is. Outputs The louder the music, the brighter the lights glow. Microphone that can hear sound  Plenary Plenary “Yesterday evening, I got home from school and turned on the TV to watch a programme on a streaming service. There wasn’t much on, so I played on my games console instead. I was tired after I finished my homework on my laptop, so I went to bed, not forgetting to set the alarm on my smart speaker. I woke up this morning and listened to some music from my morning playlist. I got to school just in time, because the satnav in the car found the quickest route.”  Plenary Plenary “Yesterday evening, I got home from school and turned on the TV to watch a programme on a streaming service.

(1–3) I can classify input and output 3 – Very confident devices I can describe a simple process I can design a digital device 2 – Unsure 1 – Not confident  Summary Next lesson In this lesson, you... Next lesson, you will… Looked at devices with different Compare using a digital tool with inputs and outputs and designed using a non-digital tool your own digital device
