Representation using binary sequences
Lesson details
Learning outcome
I can describe how computers represent data and instructions using binary sequences.
Key learning points
- Information is data that has been processed to provide meaning.
- Sequences of symbols are used to represent data.
- Binary digits are combined to create binary sequences.
- Computers use binary sequences to represent all data and instructions that they process.
Keywords
Information - data that has been given structure or meaning
Data - facts and figures in their raw form
Binary digit (bit) - the basic unit of data within a computer system that has the value 0 or 1
Common misconception
Binary is only used to represent numerical data.
Binary digits can be used to form sequences that can be used to represent any data. As long as it is identified what each sequence represents, binary digits can become any form of data or instructions.
Teacher tip
Draw parallels with other occurrences of similar symbols being used for different sequences that pupils are familiar with in their everyday lives. For example, using digits in a phone number to represent a way of contacting people rather than being used to count objects.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
