Year 3 - Computing

Designing a digital device

Computer networks

Unit Summary

In this unit pupils will explore digital devices, with an initial focus on inputs, processes, and outputs. Pupils will be introduced to computer networks, including devices that make up a network infrastructure and the benefits of connecting devices in a network.

Lesson Summary

You will learn to design a digital device.

Key Notes

  • Digital devices must have an input, process and output.
  • Digital devices work by having an input, which is the control. It is how the device receives its information.
  • The process is what the device does with the information.
  • The output is what the device does after the input and process

Vocabulary To Learn

  • digital device: an object that uses computer technology to work; it stores or processes information
  • input: data that is sent to a program to be processed
  • process: a program, or part of a program, which is running on a computer
  • output: the result of data processed by a computer

Common Mistakes To Avoid

  • A digital device has to have exactly one input and one output.

3 Quick Questions (With Answers)

1. Describe the system or process from this lesson in clear steps.

Digital devices must have an input, process and output. Digital devices work by having an input, which is the control. It is how the device receives its information.

2. Define this computing term and give one practical example. 'digital device'

an object that uses computer technology to work; it stores or processes information. Add one real device or system example to prove understanding.

3. Correct this common computing misconception.

Mistake: A digital device has to have exactly one input and one output. Correction: Digital devices can have more than one input and more than one output. They use different devices for different tasks at different times. For some tasks, input or output devices might not be required but they might be for different uses.
