Lesson Details
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.
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.
