Recall from Monday’s Lecture…
Digital data is discrete – either “on” or “off”
With 1 piece of data (e.g., a light switch), you can represent 2 pieces of information (e.g., the light is either “on” or “off”).
We call a single piece of data with two states a bit.
If we look at a bunch of bits at the same time, we can represent more pieces of information.
BITS NUMBER OF PIECES EXAMPLES
OF INFORMATION
1 2 0, 1
2 4 00, 01, 10, 11
3 8 000, 001, 010, 011, …
