● the differences between analogue and digital transmission of data
● the need to convert analogue signals to digital signals and digital signals to analogue signals
● how data in a computer is represented using binary notation (bit, bytes, word length).
Understand and use binary format and the concepts of data storage, including:
● how characters can be represented in binary format and convert whole numbers into binary numbers (zero up to 10)
● conversion of binary numbers (up to 8 bits) to whole numbers (base 10)
