Computers are reliable. After all they are the very epitomy of mathematical precision, cold logic and the result of more than 2000 years of science. They never sleep, get distracted, go on strike or deviate from their programming. Nice and predictable. As long as there are enough electrons to go about, the laws of physics and mathematics can be relied upon to keep the computers running.
Apart from the odd solar storm, power failures and worn out moving parts, the electrons keep going around, and physics and mathematics does the rest.
This often leads people to believe that IT as a whole should be equally solid and dependable. After all, physics and mathematics can be relied upon, right?
Unfortunately, this is not the whole picture.
