Bits

Hi /prog/rammers...

I'm an hobby programmer and I'm here to ask a really simple question... I tried to google it but I don't even know where to start my search

the notation:
0x00 = 00000000
how it is called?
how can I convert an 8bit array in this form?
for example how can I discover the notation or the bit pattern?
?? = 00110100
0xff = ??

can someone explain me the logic behind?

thank you...

Bruce A. Martin of Brookhaven National Laboratory considered the choice of A–F "ridiculous" and in a 1968 letter to the editor of the CACM proposed an entirely new set of symbols based on the bit locations, which did not gain much acceptance.[9]
