The computer is nothing else, just a "brain-amplifier" as one word of mouth used on the Internet is say. Believe us, is true, even more, it amplifies anything people used to have on their brains> good and bad, brilliant and obscure alike. That's why these computers are needing maintanance and care, even if some are believing the contrary.
If happens (by accident, of course), that some of these boxes are wired together, we can talk about a computer system - if any systematic thinking where hardwired in there - wich need much more attention as a sole PC. Here we're come in to the picture - you definitively need our knowledge accumulated in the past twenty-some years in this field.
