Numbers like 255, 65535, and 2,147,483,647 (I had to look this one up because I can't remember it off the top of my head, which just proves the following point) may seem arbitrary at first glance. But these are the "maximum" values for a reason. (2,147,483,647 is a little different because it's the maximum "positive" number where the other two examples are unsigned.)
<pre>
Decimal: 255
Binary: 11111111
Hex: FF
Decimal: 65535
Binary: 11111111 11111111
Hex: FFFF
Decimal: 2,147,483,647
Binary: 01111111 11111111 11111111 11111111
Hex: 7FFFFFFF

It makes a little more sense now, doesn't it? For 255 and 65535, these are the highest possible values that can be represented with 8 and 16 bits, respectively. As for 2,147,483,647, it's just below halfway to the max. It's also as high as you can get without the leftmost binary digit equaling 1.
