This could be converted into a numeric sequence of $1$ s and $0$ s $,$ where $1$ means the square is colored black and $0$ means the square is colored white. Starting at the top left of the grid and moving to the right, much as one reads a book, the message would be converted as follows:

$$

or $110010010111111011010111101011110101101010110111111010010101110010010101$

If a $"1"$ represented a white square and a $"0"$ represented a black square, would this change the meaning of the message? Explain why or why not.

Notice that we broke up the string of $1$ s and $0$ s into groups of $12,$ with each group representing one row on the grid. How would the message look if we did not do this?

Using the $612$ grid shown below, decipher the following message:

$011100000100111110001010111110010001001000001110001000001010001000001010$

What is this? $q,$

$4.$ How does the message from Question $3$ differ from the first message we looked at in Part C$?$

$5.$ Consider the drawing you made in Question $5$ of Part A$.$ Describe, in words, how you might represent the information from Question $5$ as a digital picture sent via radio waves.
