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...

Try learning atleast some basic C before you go into OpenGL
if you have time to take it slow
Also try NeHe's OpenGL tutorial, it's old but still pretty relevant and noob friendly(except for reading textures from .bmp with that obsolete lib)
