When to use 010 or 011 in binary code?
We can’t use a one without changing the entire value of the binary code. And in binary, text characters always begin with 010 or 011 . 010 will indicate an uppercase letter, and 011 will indicate lowercase . We know our letters are lowercase, and if we add that zero, we have the 011 prefix to prove it!
