Experts take this so much for granted that they forget to warn others. (* See below for an exception) It works like this: Basically, only one software application can use (open) any single software file at any one time – into your computers volatile electronic memory, where your file is located during the time you’re working on [...]
It’s happened to my clients – it CAN happen to you! Your computers and all your paperwork are destroyed in an office fire or other computer disaster. What will you do? Even if you’re prepared for a computer disaster, you’ll still have to: Deal with your insurance inspector and claims adjuster Hire a cleanup contractor and [...]
I hope online backup services aren’t your only safety net! Don’t be lulled by a false sense of disaster recovery security By using only a remote backup service like Mozy or Carbonite.

And the biggest aren’t from the Internet. Let me scare you first and reassure you later. Consider a few common scenarios from my computer [...]
It’s gonna get hot! Squeeze 410 Million transistors onto a CPU (Central Processing Unit) chip that’s smaller than a dime and you’ve got some serious heat to deal with. Note that the CPUs above are shown laid out on their production “wafer” – before being cut up into individual “chips”. The latest chip fabs (fabrication [...]
