explain how and why digital systems represent integers in binary

Elaborations

• AC9TDI8K04_E1 - explaining how whole numbers can be represented in binary, for example counting in binary from 0 to 31, and recognising that one byte = 8 bits, which can represent from 0 to 255
• AC9TDI8K04_E2 - explaining how digital systems represent data in binary, for example by converting a character to its Unicode value, then converting that value into binary
• AC9TDI8K04_E3 - explaining how circuits can perform binary operations represented as on/off states, for example showing how circuits with 2 switches can represent AND or OR gates

Achievement Standard Components

• ASTEC7803 - They acquire, interpret and model with spreadsheets and represent data with integers and binary.
• ASTECTDI7802 - Students acquire, interpret and model data with spreadsheets and represent data with integers and binary.
