I know what you're thinking... "did he just say 'binary data'? Like, 1's and 0's?" Well, yes, yes I did. If you're like me, the last time you actively had to do anything with straight binary data was in college when you were learning how to convert between binary to hex to decimal and back again. I would imagine that most of us run into hex somewhat frequently, but that we don't actually have to deal with binary data as often.
