Content Description
explain how and why digital systems represent integers in binary
Elaborations
-

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
-
2
explaining how digital systems represent data in binary, for example by converting a character to its Unicode value, then converting that value into binary
-
3
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
