Now you can help me out…

I need to write up a comparison between Windows XP and Linux security. I’m on windows atm and I don’t know what to write about it, other than it’s real vulnerable

C and E are wrong for sure, and patch panels were used for phone calls (rj-11 is phone cable), still I would rather take b aka rj-45) 19.ACE 20.B 21.x again

I’m not sure about all, but should be over 90% correct :l
