How many patterns can be formed with a single bit?

### A good answer might be:

Two ― 0 and 1 (or "off" and "on", or "false" and "true", or ...)

# Patterns of Bits

A bit can be 0 or 1. With one bit there are two possible patterns. How many patterns can be formed with two bits? Here is a complete list:

>             0 0
>             0 1
>             1 0
>             1 1

Looks like 4 patterns.

### QUESTION 2:

Is the pattern `0 1` different from the pattern `1 0`?
