Man I don't mean to sound like an ass, but so what? You know the definition of a modem and stuff about printers. A+ certification is a pathetic excuse in the computer industry. Neutrino and I have made a mockery of many A+ certified techs. In fact I used to have a boss that was A+ certified, he couldn't build or fix a computer to save his life, but he sure could tell you what PCI slot was.
BTW: I am mostly ragging on the A+ cert itself, neither you nor your intelligence. I am sure you could get a more reputable cert and I suggest you do.
