How do hexadecimal numbers or whatever work?

I like the Base-Π number system :p

Agh clout with his complications.

2^16 is 65536, so 65535 is the largest number you can store in two bits. 15 to store the digits and 1 to store the information about the file.

Are you sure you're not thinking of two bytes? Because the maximum 2-bit value is 4. 2² .

Probably. At least I didn't refer to nibbles! or is it nybbles?

Is that number special or something? 'cause that's the maximum PM's I'm allowed. I'm like totally freaked out now, it's like those numbers in Lost.

Just remember that 2^x are special numbers in computing; 2, 4, 8, 16, 32, 64, 128, etc... That way they won't scare you again.
